It depends on whether the executable in question was compiled
with Borland Turbo Pascal. I ran into this issue trying to run a
Win-16 version of an OCR program that had run just fine under
Win-OS2 when I still had a PPro-200 in my system, but which
ceased working after I upgraded to a P2-450. Someone in Germany
sent me a couple patches, one of them from C'T magazine. They had
no affect on the executable, evidently because it was *not* Borland
TP in origin. It would also no longer run under real Windows.

A bit later on, someone else put me onto BREMZE. It is shareware,
with a nominal registration fee, and consists of two alternate TSRs.
I tried one of them, determined that it worked, but that the other one
was more appropriate for this situation. This was enough for me to
decide to register the program, but I have not gotten around to
pursuing the matter further. BREMZE is (I suppose) a successor to
an earlier generation of DOS processor-slowdown utilities like
AT-SLOW. It can be used in a DOS or Win-OS2 session. However,
there are a number of variables, and you will probably need to
play around with it.

Let me know if I can be of any further assistance.
