Quite weird. I didn't noticed anything like this, but reinstalling the whole system because of clipboard is just insane :) I suggest reinstalling (remove & install again) all KDE related packages. If that doesn't help either, try to run kde with removed (but backed up!!) ~/.kde, which I don't think will be of much help, but you can try. Dave
