OK Bjørge,
here is the code I use for a simply 10x10 map
Please modify it so it can make use of the
off-screen bitmap with BitBlt functions?

Eh...well, something must have happened since my last "fast paint" attempt...maybe something with hardware:
- when I tried to do this opearation on an offscreen bitmap, it turned out to be some 10% slower !

I'll have to go back to my original sources to see if I have missed something - but I'm afraid not.
