Also, I don't think I'm running any A/V software (Windows keeps nagging 
me that my system is *not* running A/V).  I uninstalled it to see if 
that was the problem before reporting it to this list.

Also#2: I'm seeing this problem on a Win7x64 machine, but I also have a 
WinXPx32 machine which has started exhibiting the same symptoms.  That 
one *is* running Symantec A/V (which I've never had trouble with 
before).  It's a work machine, and I don't have permissions to uninstall 
A/V, but I'll see if I can convince the IT guy to uninstall it for a 
while to see if that resolves the problem.
