Ok, so it did work once?  You saw some blue dots rotating around one time?

Anyway, very encouraging to me.  Sounds like my code is not to blame
after all... but which code is to blame.

Also interesting that the common factor seems to be the core 2 duo.
Do you have new-ish GeForce drivers?  I haven't updated the drivers on
this machine where it works for a good long while.  And it sounds like
your card is similar era.
