OpenSuSE 11.1 + KDE 4.2 or 4.3 + rapid alt-tabs -> lockup

Hi all,

I am running OpenSuSE 11.1. The problem occurs with both KDE 4.2 and 4.3beta.

I’m not sure if the combination is triggered by alt-tab, or some combination of alts and tabs (e.g. could be alt then alt then tab), but if I try to tab repeatedly amongst a group of windows and hit some combination of alts and tabs repeatedly (i.e. my finger slips on the alt, or I hit it twice etc), then the interface becomes unusable.

I cannot click into any window. Instead, the mouse goes into move mode (i.e. clicking and dragging windows makes them move). I am unable to select text boxes etc. Only solution I can find is ctrl-alt-backspace to kill X, after which point you can log in again.

This is REALLY annoying. Suggestions? Thanks
