Vanishing Point - Bug?

Still no response???
Just a simple
"yes I have experienced this but have no idea what's causing it" or
"Nope, no problem here"
or
"no response = known bug"
would at least help............

Nope, no problem here.

Never seen it.

Thanks for the two responses.
So it appears to be just me with my two systems.
How very strange!
Am I running enough memory? (2GB - 55% to Photoshop = 973MB)
