If you mean "runned under GUI", then this may be explained as slowdown

This bug is in CRT unit: Borlands programmers implement delay() in such
way, that it loops given count of iteration for each request millisecond.
For this, when program starts, CRT units measures how much of iterations
performed during millisecond. Trouble is that on faster computers there is
too much of iterations and in next calculations result is division by zero
(which in TP called "Runtime error 200").

There is some ways, how to fix bug in TP library itself and how to fix
already compiled programs. And this not depends from OS. For example, take a
look at:

Also, for fixing programs, compiled by TP/BP, I very recommend TPPATCH,
written by Andreas Bauer <andi.tio hit.handshake.de> (unfortunately, don't
know its URL).
