I think I found another bug (my fault in first place)
SYNC RATE 0
SYNC ON
...do some complex 2D things on screen
...
SYNC
The SYNC does not refresh the screen, only after SYNC OFF I was again able to see anything refreshed on screen. Hope, I d not need to send a 5 Meg compilat (EXE=Compilat) again to Lee and this bug can be reproduced easy.
Okay, now after I know why my prog freezes, I can again make a workaround.
Patch 3 is still much better bug-wise than Patch 2, thanks to Lee for the efforts, and for fixing this array-Memory bug.
