If you click the X in the top right corner, the current window closes. Clicking it again does nothing until you have manually changed windows.
Closing a window with the X in the corner seems to stop it coming back again (unless it was the first one closed).
For example:
- Connect to server, with a perform of:
JOIN #Dataforce,#Test,#Test2,#Test3
- Close #Test, #Test2, #Test3 using the [X] button. (Due to the first part of the bug, you'll need to change window between each click of [X])
/reconnect
- Only #Test re-opens. (Client silently joins #Test2 and #Test3)
