plasma hangs - zoom out but no zoom in
I have just installed (emerge) KDE 4.3.5, and have a bit of a problem. I click on the 'cashew' in the upper right corner of the screen and select 'zoom out'. The first time around I get a screen with my current desktop in the upper left quadrant with a menu over it. I cannot zoom in again. 'top' shows plasma getting 70% and X 30% cpu.
The three-finger salute gets me back to the command line. The next time I try, the menu box is there, but empty, and I cannot zoom in again.
In order to get KDE to work I need to replace ~/.kde4. Shotgun solution, I know, but I don't have the expertise to be more specific.
