My title states the problem: I have openSuSE 11.0, with KDE4.1 and Compiz, very pretty, on my HP Pavillion dv9205us (4GB RAM, nVidia w/ 256M).
When I close an app, its name stays in the taskbar. Right click yields a menu, although nothing happens if I click a menu option. If I open another app, it appears on the taskbar after the bogus one, so I’m losing panel real estate.
What makes the matter tolerable is that if I switch to a different desktop, and then back again, the taskbar is correct, but I wonder if anyone else has had this problem and fixed it, or if this is just a bug.
