Hello:

Suggestions for this problem have already been offered on the net, but
none of them work for us. The suggestion to use the Microsoft in
Graphics mode is a little bit confusing, can someone please elaborate
on it??? 

Windows applications all run in Graphics mode, it is only for
the non-windows applications that you have the choice of the mode,
i.e., text or the graphics mode. Please correct me if I have
misunderstood some concepts.


Actually this is what we have found out:


For us, the Messages are received when the windows run in STANDARD
MODE. But the moment we switch to ENHANCED MODE, it starts eating up
the SEND Messages. I think this is what is happening, again, someone
please correct me if I am wrong:

When the "Send Message" is received by the network workstation, it has
to be displayed on the screen, which would be done by generating some
Interrupt signals. In Enhanced mode, it might so happen that these
and the other DOS interrupt signals are being consumed by the Windows,
to enable it to run faster, and hence the broadcasted message will not
appear on the screen. If you know exactly what interrupt signals are
being generated, may be there is a way to tell windows not to consume
that interrupt signal. i know there is one such option to tell windows
not to eat-up the DOS Interrupt 2A. But we cannot make windows receive
messages in enhanced mode yet......

Windows and Novell Guru's please comment on this theory .....


Thanks
