Several users complain it crashed immediately on their machines
including windows 95, 95 OSR2, 98.
It says somthing like:
MyProg cause an exception 10H in module MyProg.exe at
0137: 0040e864
Stack dump:

I tested the software on my company's windows 95, OSR2, 98, xp machines and it works
fine. I just can not reproduce those crashes, and they are too far away for me to be on site.
Anyone has a clue on how to debug this problem?
I appreciared your input.

I used c++ 6.0 for compile.
