I am using 11.04 and I have global menu's disabled (don't remember which method I used to accomplish this). I have the system tray set to allow all apps, using a method I found on Webupd8 and I have "minimize to tray" add-on for Mozilla Thunderbird which is set to close Thunderbird to the system tray instead of quitting/closing it.
Problem: If I minimize or close any application to the system tray without first un-maximizing the application's window, I am not allowed to grab any open app's window that is maximized by the title bar using the mouse. I have to first un-maximize the app to move it. But, if I minimize an app to the unity launcher bar instead of the system tray from any position (be it maximized or not) I don't have any problems.
How do I make the applications behave the same way when minimizing/closing them to the system tray?
