- We read the modulos from the MyScreen->ViewPort.DspIns->CopLStart.

- You guess wrong! ;)
-

- >i.e. , write modulo = 40 for 320er mode and you get display-rubbish!
- We don't cacluate the modulo from ddfstrt/stp values.
-
- Problem GONE! :-)

-
- Is this slow?
-
- ChangeVPBitMap(&MyScreen->ViewPort, ActiveBM, MyDBI);
