"At the moment?" How are you logging into the machine if you
are 2500 miles away? Is it on the net? Yet you have no firewall other
than XP's builtin, and no other security software? Could it be possible
the machine has been hacked?

When I do it interactively at console, I run process explorer (a GUI).
Hey, just noticed, it's in the task manager too, on the processes page, rightclick
and make sure only 1 cpu is checked on your "parent" process -- i.e. if you run from
'bash', setting the affinity on bash will also propagate it to the children.
In the response after yours, by Oliver Walsh, he mentions another tool
that modifies "exe"s to limit them to a particular cpu -- that's another possibility.

Could that provide better support for multi-core cpu's? Dunno.

Urg...I usually remember visits to win-update...they are usually painful.
Takes hours for them to download as is constantly trying to go around my
proxy and go direct with each file -- after taking forever and timing out on
several servers it eventually gives up and downloads it through the proxy,
but it slows down each file download to a few to several minutes...
Seems to be a new feature with SP2....didn't have the problem in SP1 for some
reason, but MS mucked heavily with SP2's network stack and messed up more than
one network related program.
