My application runs well on NT, 2000 and XP, but crashes on 98

Hi!

I have an application that runs well on Windows NT4, Windows 2000 and
Windows XP, but it crashes on Windows 98.

I don't have any environment on the 98 machine I can debug the application
in.

Any ideas what I've done wrong.

My application is compiled with Borland C++ Builder 5

Thanks in advance, H?kan Andersson
