Windows 2000 runs the processor in protected mode all the time. And it is impossible for one process to write in the memory belonging to another process without windows recieving and exception from the processor, which results in Windows saying there has been an access violation or general protection fault or whatever Windows calls it nowadays. >This is of course assuming that you dont have any hardware trouble or other >silly stuff on the PC. Sure. If you experience crashes, it is probably either a bug in the program, or faulty RAM. /David
