When Matlab fails, can you still open up other applications without any
problem?

I've been struggling with my office machine as of late--whenever Task
Manager shows I've got around 20,000 handles opened (in the Performance tab,
on the bottom left) things start to fail randomly until I either reboot or
bring that number back down by closing applications. Menus stop redrawing
themselves, buttons with show up without captions, shortcuts won't launch
applications. The instant I close a few apps, things go back to
normal...until I reach that 20,000 figure again (sometimes it's closer to
18,000, FWIW).

It doesn't make much sense on XP on a machine with 1.5GB RAM, but that's
been my observation...
