KDE4: Bad taskbar icons

Hi All,

I occasionally close windows which close fine but stay on the task bar.

e.g. at the moment, I have 2 x opera, and two times “Desktop Settings” icons on the taskbar.

These programs definitely aren’t running (not listed under ps -A), it is just that the icons on the task bar won’t go away.

I just upgraded kde4 to 4.1.something, but the problem is still there.

Any ideas?

many thanks.
