startx causing XP (Media Center Edition) blue screen?

Forgot to mention that before the bluescreens, I saw (but couldn't capture
accurately) errors of the form:

x error bad window invalid window parameter (and alternately 3 and 5 on the
end of these types of messages).

Not sure if that is relevant, but I did see them.

Well, I've tried upgrading the video drivers as well as the network drivers.
Still get the blue screens.  So, suspecting my wired network card drivers, i
then used my wireless network card.  Same.  Blue Screen.

The only other thing that I can think of was brought up in other posts - I
have Zone Alarm 5 and Norton Antivirus 2004 Pro running.  Anybody else out
there getting XP blue screens with cygwin when running ZAP and/or NAV?

I suspected as much, too, except that I've exahusted (I think) those
possibilities.  I'm fully updated as far as Windows Update is concerned;
and, I pulled down the latest video & network drivers from the respective

All of this is unfortunate; even if, technically, it's Windows that has the
problem, the net result is that I can't use cygwin, unless I can figure out
what is causing the problem, and take action to correct it....
