Unable to move windows in KDE, FreeBSD 5.2.1

[Jay Moore]

I'm not sure exactly when this happened, but I can no longer move or re-size 
any windows. Open windows behave normally otherwise - I can minimize, 
maximize, close, move to another desktop, etc, etc. They just can't be moved 
or re-sized.

Is this a known problem, or just some weird anomaly requiring a re-startx?

Oh - I'm using XFree86; this is a 5.2.1 installation.

Thanks,
Jay
