hi Mike.

hmmm.  AGP aperture size.  is that something that can be modified in setup?
i'll take a look.  maybe i'll stumble on it.
what specifically happens here is that while the video window and the VIC
window are overlapping, bad things happen (almost like a recursion gone wild).
once they are no longer overlapping, the problem disappears.

thanks.
