I'm having problems with our VB 4 16-bit app in NT 4.0 with the NT
Virtual DOS Machine.  The app runs on all WINxx without problems and doesn't
croak on all NT installations.  There seems to be nothing in common from one
machine to another where it crashes and takes the VDM with it as well as any
process running under the VDM.

Do you know of any conditions where a 16 bit app will crash and kill
the VDM?  Can you recommend a tool or process to narrow the problem down?

I've tried the Checked/Debug Version of NT but it proved to be of no
help - or I wasn't using it properly.

TIA - Richard

I wouldn't use VB4/16 on 32 bit systems. The implementation is very buggy,
crashing also the Win95 16 bit subsystem easily.
