System running slow since install of KDE

[Jared Buck]

I installed the KDE environment onto my install of FC3 a couple days ago
just to see if I liked it.  Since that install, whenever I log into
GNOME, many of my applications (particularly up2date and web browsing)
run very slowly.  Is this a problem with having KDE installed?

If it is, how can I remove KDE from my FC3 installation?  add/remove
programs apparently doesn't allow you to remove KDE from the machine.  I
would like my programs running fast again, and I think KDE is the
culprit.
