My Comp is pretty fast; running a Athlon 2600+, with 712 DDR Ram. Funnily enough, KDE seems to be running quite smoothly now. I fear it will revert to doing the same thing when I restart my computer again, next time, but I'll wait and see. I'll try killing the KDEinit, like you said.
(Though, after this has happened, open office doesn't seem to want to open in KDE anymore (works on the other DEs))
Thanks for your advice.
