This note is for users of OS/2 Warp who find that use of SCAN.EXE causes
the THDPRO.EXE (or other) window to close without any apparent reason.
After much investigation, I must admit I am unable to figure out "why"
SCAN 2.?.? closes an OS/2 session.
However, I have found, that for some unknown reason, I am able to stop it
from doing so if I run "SCAN *.*". After running this in an OS/2 window,
SCAN.EXE thereafter seems to work fine. In turn THDPRO.EXE has no difficulty
running it without the window closing.
If the window (or session) is closed and then opened again, you will need
to run scan.exe in the newly opened window (session) in order prevent SCAN.EXE
from closing it.
This has proven to be the case on my system for both a VDM and a dos
session. I cannot however guarantee it will work for everyone else.
