isnt a OS issue (maybe I try win 98 too, just to eb sure). I have changed Graphic card to ATI X800, that wasn't it either. Isn't even a delphix issue.

Its a delphi issue. I have no idea what it is and have all but give in. Will get hold of borland delphi 2005 and see if that too has this strange "bug".

Delphi 7 no change from 4, the same. On idle loops exact the same as the timers. Somehow iterations are being limited. Its all messed up and crazy. I am stuck well and truly.

Will keep you posted

Edit:

Borland 2005, same problem. And my my what an AWFUL GUI 2005 has...I will never ever use that!
