After upgrading to 12.10, several of my apps won't appear on the launcher, including eclipse and idea. They are not in the Alt+Tab switch list either, so I won't be able to switch to another app and switch back.
I checked on this website and found no similar questions about 12.10, so I re-install the 12.10 from scratch. But this problem still exists. And even gnome-terminal won't appear either!
Anybody has similar problems?
