Hi Dale,
   That seems way high to me but I cannot do a real comparison here as
I haven't had a 32-bit X86 machine in 4-5 years. My current box is
tied up running 3 copies of Windows at the moment and is using pretty
much 12GB at the moment so I'd have to reboot to take any reading.
However I seem to remember only 350MB being used right at the point of
logging into KDE, but I could be wrong about that.

   Maybe post a few numbers:

1) What is used when you first start KDE
2) The additions for a few common apps.

   I'd be happy to compare mine to yours later today.

- Mark
