16-bit DOS program lost video

[Guest]

I have a user who, when he runs a certain DOS program, gets no video, i.e.
graphics display. You can see the program running in taskmanager, but the
program screen has just disappeared. This is a program which has run
successfully for years prior to this and is running successfully on the exact
same machine throughout my office. I tried the ole expand config.nt,
autoexec.nt & command.co to no avail. There is no error message anywhere, and
this just happened out of the blue. it is on a Dell Optiplex GX520, XP SP2
with all critical updates.
Any help would be greatly appreciated

Does it work on another computer?

About a year ago I had a user in our medical imaging department that
was running a DOS program on Windows 2000. One day it stopped working.
She claimed it worked at home on her XP machine. I went home and
downloaded it from the EPA's web site and it worked for me as well.
I'm pretty sure it was a rebuild situation.

Adam,
Figured it out. It so happens that the Blackberry Desktop Redirector, which
was recently installed, for some reason blocks the graphic display of the
ADOSS program. Once I toggled it off, up came the display. I fugured this out
partly because when I would go to reboot the machine when task manager said
ADOSS was still running, the graphic display would pop up as several of the
running services would shut down, including the Redirector. Go figure. Why
would an emial redirector block a DOS graphic display? Got any ideas on that?
Thanks for your reply, though. I appreciate it.
