With some gnome apps which have a full-screen mode (e.g. "eog" or "totem"), the buttons on the title bar for "close", "maximize" and "minimize" don't function after returning from full-screen to normal view.
Steps to reproduce:
1. Start compiz, then open an image in eog ("Image Viewer").
2. From eog's "View" menu, select "Full Screen".
3. Click "Leave Full Screen" to return to normal view.
4. Click the close button on the title bar of eog.
Actual results: Nothing happens.
Expected results: eog should close.
This happens (100% for me) in eog and in totem. I am using compiz 0.51 with Ubuntu 7.04.
I can't reproduce this on recent versions. Please reopen at bugs.opencompositing.org if you're still experiencing this. Sorry for the inconvenience.
