>It seems to be all. Up until last week we didn't have any clients using Workstation to access our application then we got one. When we received the error report, we bought a copy, installed it on an older PC we had laying around and reproduced the error on the fresh install.

So you had the same situation on more than one NT Workstation 4.0.

The you have the service pack 1?

There might also be a problem with the Visual FoxPro installation over a NT 4.0.
