Are you using WB 1.3? 

I had problems with some programs that opened custom screens locking up if
I flipped or moved the screens up and down. I especially had problems with
the VLT terminal emulator - I thought it was buggy, but then I read about
a bug in the Intuition (or whatever.. Graphics?) MakeVPort routine. There's
a little 16 or so byte patch I use in my Startup-Sequence and I've never
had the problem again.

I'm not sure that's the problem this fellow is having... anyone else know
more about this?
