Second user suffers (OpenInsight Specific)

I have a client with a multi-user version of our OI 3.3 app on a network with Win95 workstations and a Win NT 4.0 server. Now they seem to have problems with simultaneous access. If they log on from two different workstations it looks like the second user suffers, no matter which workstation was first and which was second. (I don't know how much the first one suffers, but at least as long as he is alone everything is all right.)
What happens with the second user is that he might not be able to open a window with the same table as the other user. Or he may be able to open it but the system hangs. Or he may be able to do what he wants but with everything running slower. (The table itself is OK according to LH Verify.)
Networking and stuff is not my force, my colleague who knows more about it is away for several days, the client is more than a hundred miles away and not too computer literate, and I'm at a loss where to start. Has anybody seen similar symptoms? Can somebody suggest tests I can run to help me close in on the problem? Any help is appreciated!

Oystein,
What network driver is the application running? Is the network heavily trafficked? I've noticed that OI (without either the NLM or NTS) is *very* sensitive to network traffic–even more so than AREV.
I've also seen this kind of slowdown with the NT Service on a very lightly loaded network; it was related to running multiple "stacked" protocols (i.e. IPX -and- NetBEUI -and- TCP/IP) and as far as I know it has never been resolved. I have no idea how to "unstack" protocols, at least not at the Win95 client level. Getting rid of any one of them was not really an option.
Hope this sheds some light,

Alex,
Thank you very much for your response. So far I haven't heard from my client. I've only faxed him the information you gave. So I don't know if the cause of his problems is among your suggestions. (But at least I wanted to thank you before I forgot.)
