7.10 Server freezing

[Peter]

Cool about your nephew.
I could also killx on my server when I"m not there...and have top
running. That's a good idea.

I assume they're running openoffice and firefox. We haven't done any
teaching about available software; we just plopped down the edubuntu
instead of the winXP.
