Thanks Mark,

Apparently the problem is specific to Windows2000 on this machine.
Another reader with Win2000 reports the same problem I have on the
ThinkPad T20. I reported this to Mathematica tech support, who simply
ignored my last email.

I wish I had Windows98. Windows2000 is driving me crazy; I hate it.
