One thing that it could be is that the profiling pattern is different for AMD processors. Even loops sitting on INKEY$ do not misbehave. On my system, it works perfectly (I am using a Dell with a P3-1000 processor and 512 MB of RAM), and QB & QB programs do not hog CPU time when they aren't actually processing. However, the successfulness of this profiling is system-dependent. When this works, it allows it to suspend the program when it is doing nothing but waiting for input (in much the same way that a Windows program becomes suspended between keystrokes). ![]() I believe the NTVDM makes use of profiling to determine when the DOS program is in an input loop.
