I have a problem that seems to be related to the new Gnome desktop. I've been running Eclipse in Mint 11 for awhile just fine. I installed Mint 12 with the new Gnome interface on my laptop, and Eclipse afterwards.
The problem is that some windows in Eclipse do not have the X in the top right corner to close the window, and there is no way to close it. Specifically the Android SDK manager.
The X shows up and works fine on my Mint 11 install.
When the window is up, there is no way to close it, or Eclipse afterwards. Right clicking and closing doesn't work. Using the process manager doesn't work. Nothing works. I have to reboot in order to close Eclipse.
Considering that Eclipse works just fine in other desktop environments, this seems to be a problem with this environment rather than Eclipse. Has anyone else seen a a similar issue like this? Is there any solution?
