Hello everybody. Test.exe is a small programm so that you can see, if one of the Programms you have running is eating up some CPU-Time from time to time. Start it and you'll see a white line moving slowly. If it flickers, I mean it disappears for a frame, then one of your programms like Memsnoop, the Systemmonitor or PaintShop Pro is eating up time. Try to find out which Programm it is and switch it off, then will the Vertical Blanc Interrupt (AYS_VBI.ZIP) work. By the way. Please mail me the name of the Programm which made problems. I'll make a list of this programms. Thanks for your time, Yup .
