View Full Version : [ubuntu] How to close windows FF/Thinderbird with "X" ?

April 30th, 2013, 10:48 PM

After upgrading from 12.04 to 13.04 I can no longer close, minimize, maximize windows such as Firefox, Thinderbird ... those buttons simply are not responding, they go kind of greyish when clicking on them.
I need to click on lets say Firefox on the bottom panel to have it minimized, then click again to maximize it, and then those buttons on the left top side work ...

How to fix that ??

BTW, I'm using Gnome Fallback, which I've reinstalled, but that not help.
