"Run Command" (ALT+F2) Freezes

[Fratyr]

Updated system to KDE 4.3.2

When opening Run Command ( ALT + F2 ) and typing something in, I did: "nvidia-settings"
It just stuck and not responding, but stuck with the same color, it's not grey or brown, I just can't control it, can't close it or open a new one.

Any ideas?

Run as normal user, not root:
mv ~/.kde ~/_kde_backup
after that reboot

KDE will recreate its settings for your user and everything should work fine.

If problem stays, go to CCMS(Compiz Manager) General/Commands or Commands -> Command 0 -> krunner, Run Command 0 key combination: ALT + F2

Reboot.
