DOS application in a window... HELP!

[Fil Feit]

Hi all,

I have a fairly complex DOS-based application that I run under windows
in enhanced mode without any problem. However, when it is placed into
its very own window, it crashes violently (altho dr. watson sees nothing
wrong with the app). This is only under 3.1. Under 3.0, everything is
copacetic.

Anybody have or know where I can get a list of what 3.1 is sensitive to
that 3.0 is not? This has been driving my nuts since 6 April!

Thanks
