MS Dos programs

[Matthew]

Hope you all can advise. I am running a program in XP
that is evoking a error meassage suggesting a 16 bit error
subsystem message. I followed the required steps in the
MS knowledge-base, no luck. The program worked in any/all
MS operating systems before, but no does not. Not sure
what is going on.

What's the DOS program you're trying to run?

Start -> Help and Support, search on "compatibility mode".

However, if your DOS program actually exited Windows to get into
real-DOS mode because it needed direct access to hardware then it won't
run under any NT-based version of Windows. If it ran is a DOS "shell"
*within* a 95-based version of Windows then it should run under Windows
NT4/2000/XP as well, but you may need to use compatibility mode (pick
whatever was the version of Windows that the DOS program used to run
under okay).

Mailroom, an old Text based e-mail program. Never had a
problem before. Has run in any and all MS versions. All
of a sudden the error message I mentioned and will not
open.

*May*, not 'should'. The DOS environment in 9x systems allowed free
access for the 16 bit program to handle hardware for itself, and XP
absolutely prohibits this. I'd think it likely that a mail program was
doing just that
