I await an answer with great interest to this one. Since my desktop became a
bit cluttered and the number of files built up my desktop painting etc is
slow especially if the internet is being accessed via eth0. Eth0 and desktop
painting even interferes with sound. No such problems on suse 9.0 and the
same kit. I often have 20 or more Konqs up.

It just like a screwed up windoze installation.
