Documentation of some issues
You may want to check if Irc logging is enabled in the Debug Window
Extra - Debug window - Checkbox: Irc log), which should
be disabled by default, but can lower performance if checked.
Note: If you don't use global hotkeys you don't have to worry about this.
If global hotkeys don't work, but there is no error message about it, make sure that you actually have global hotkeys enabled in the Hotkeys settings or in the menu "Extra - Options".
Global hotkeys should usually work on Windows, Linux and Mac. It's possible that they don't work in just some contexts, for example some games.
If you get an error message related to global hotkeys:
Extra - Debug windowfor errors related to global hotkeys. It's possible that there was some error with the native library or that your platform is not supported properly.
If you loose your settings (or part of it like just the Addressbook) then either they weren't saved/loaded properly for some reason or you changed your configuration and your settings directory is not the same anymore.

/openDirto open it) and whether that's the one you used before (there should be quite a few files and folders).

The image/sounds folders are based on the current Working Directory, which is set when you start Chatty. More Information..
If you repeatedly get disconnected because of possibly invalid login
data, please go to
Main - Account - Verify login.
This will send a request to Twitch to check if the access token is valid.
If the login data is valid, then Twitch may just have temporary problems
and you should try again later. The same goes for when the check itself
fails because it can't reach the Twitch API.
If the login data isn't valid, you can just remove the login and request new login data. Also see the section about login for more information about invalid logins.
Another reason may be that you are connecting to the wrong port.
It's possible that your internet/firewall doesn't like the port you are
using to connect. By default it tries to connect to
first. Twitch may also have changed the ports. You can check Twitchstatus.com
(not an official Twitch site) which chat server/ports are available (make sure to use an
irc.twitch.tv should resolve to the available server IPs, so you normally
shouldn't have to enter an IP directly (for main chat).
If you are using a shortcut to start Chatty, also check any custom server/port you may have defined there using commandline parameters.
If you get an error getting login data, see What to do when getting login fails.
If Java encounters a character that is not contained in the chat font you currently have configured, it will try to find it in the fallback fonts. You can add your own fallback fonts if you need to be able to display more characters than by default.
The Java fallback font directory is located in the Java Runtime Environment
(you may have to create the
/fallback directory yourself):
To find it you can use the command
output the full path or the command
directly open the path in your file browser. The commands have to be
entered into the Chatty chat inputbox.
The Windows Standalone already contains the Unifont fonts as fallback fonts by default.
Note: If you set the
setting to something other
than a Java logical font (which is currently only possible through
setting commands, changing through the Settings Dialog is fine), then
the font fallback mechanism may break.
Chatty.exe uses the bundled Java (JRE) in the
directory to execute the
Chatty.jar in the
directory. If you have issues executing the
Chatty.exeand the bundled Java in the
runtimedirectory may not be compatible or they weren't installed correctly. Manually delete the
runtimedirectory and re-install the Standalone version and make sure it installs or extracts fully.
runtime/lib/extdoes not exist.
You need to have at least Java 8 JRE (Java Runtime Environment) installed to run Chatty.
If you try to start Chatty by double-clicking the
first make sure that
.jar files are associated with Java,
and not some other program like WinRAR. The icon of the

If you are sure that the
Chatty.jar is actually started with
Java, but no program window appears, it may be that an error occured before
the window (GUI) could be created.
Running Chatty from the commandline has the advantage of being able to get messages from before the GUI is established. It also may work when Java isn't integrated into the OS correctly (but is installed).
Chatty.jaris located. Click on
Open command window herein the context menu.
java -jar Chatty.jarand press Enter.
When you enter the above command and Chatty starts correctly (but doesn't
when you double-click the
Chatty.jar), this may mean that
Java isn't integrated into the OS properly. You can create a
shortcut or a .bat-file to
start Chatty similiar to entering the command above, but much more
If Chatty doesn't start when you enter the above command, check the commandline window for error messages. Send a screenshot of the commandline window along with information on what other things you tried if you require further assistance with it.
If the integration of Java into the OS may not be correct, and you want to try to fix it, you can try this.
Open a commandline window and enter
assoc .jar which should output
.jar=jarfile and enter
ftype jarfile which should
output something like
"C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*
Could not find the main class. Program will exit.)
If you experience this when entering
java -jar Chatty.jar
in the commandline, then it probably can't find Java because it's not in the
PATH environment variable (that defines where to look
for programs of which only the filename has been entered, not the whole path).
You can enter
PATH in a commandline window to check what is
in it. It should show a list of semicolon-separated directories, one of which
should point to Java.
See next section. Of course you'll have to navigate to the folder manually.
Some people experience issues with stuff in Chatty not being drawn correctly (e.g. on top of eachother, areas not showing). This is probably a Java bug that is system-dependant in some way (possibly OS or graphics driver related, it's not really clear). There is no definite solution for this, but there are a few things you can try:
javaw.exeto an ignore list or disable on-screen display support if possible
Settings - Other - Disable Direct3Dsetting is checked. Maybe also try
Disable DirectDraw, although it should be redundant.
-Dsun.java2d.d3d=falseparameter when starting Chatty, which does the same as the
Disable Direct3Dsetting, but adding it as a starting parameter seemed to work better for some people. To do this, create a shortcut and add the parameter, similiar to this (obviously adjusting to your paths):
javaw -Dsun.java2d.d3d=false -jar "D:\Chatty\Chatty.jar"

When using a High-DPI monitor or changing the monitor scale setting in Windows, you may experience blurryness in the UI since UI scaling is not very well supported at the moment.
If an app does not handle scaling Windows will attempt to scale up the app automatically, which will usually not look very sharp. There are different ways to tell Windows that Chatty/Java should handle the scaling:
Once Windows lets the app do the scaling, there are different possibilities:
You can change the "UI Scaling" setting under "Main - Settings - Other"
to force a fixed scaling. This may not always work. To avoid blurry
images and other UI issues a scaling of
1.0 is recommended
(you can change "Look", "Font" and "Emoticons" settings to scale up
fonts and emotes).
If Chatty can't access some files (e.g. sounds), you may have to give the
JAR Launcher additional access. Go to
System Preferences - Security -
Privacy - Full Disk Access and add the
to the list.
