I had the same probs. So here is the
temp. solution until you fix the problem:
Go to DEVS:monitors & select icon info
for BVisionPPC monitor. Then there you should
have following tooltypes:
BITMAPCACHE=YES
BOOTLOGO=YES
PACKED24=NO
SCROLLMASK=YES
PASSTHROUGH=NO
VLAYER=DESTRUCTIVE
If you set BITMAPCACHE to NO - there will be
no vertical lines. Or you can chose 16bit
screen.
If you have some more probs, email me.
