I'll give it a shot when I get the chance.  Unfortunately, I'm bogged
down with meetings tomorrow morning, so it will be at least 14-15 hours
from now.  Perhaps some other adventurous person can pick up the ball in
the meantime.

My test system is 933Mhz PIII, IDE, 256MB. The apps are Mozilla 1.3 and
Evolution 1.2.2 running under KDE 3.1.

Thanks,
Steven
