Hello fellow Ubuntu users, I've ran in to a problem. I'm sorry if I'm not using the right therms, but it seems that the shell of my ubuntu is broken, I've lost the 3 graphic ways of (windows-buttons) resizing and minimize my windows: http://i.stack.imgur.com/aZzQB.png (sorry I can't post images since spam protections says that I'm a noob)
The problem is that I cant minimize m empathy chat windows, and the same goes for my skype. I have to Alt+F4 them to close the windows, but sometimes I just want to minimize them.. please help me out?
I did try to change shell and back to GNOME, but it did not help really :(
