Dear Robert, now I see that my KeyRepeat function seems to have a second problem. If I set LMSetKeyThresh( 0 ) then the KeyRepeat seems to be off, but the steps after that are as long or as short as set in the preferences choosen. Well, that is not the work it should work like. The KeyRepeat should be turned on with my procedure call "fn KeyRepeat 0" and - that ´s new - with very low steps between the keys after that, and it should be turned on if I call "fn KeyRepeat 1", and set back the original values to the steps after that too! This is needed to get a quick gameplay of course independend on what settings are set in the preferences! Markus, curious looking
