Donny,

Yes, we were having the same problems before we installed SP4. I hadn't heard of anyone having problems with VFP running under NT workstation, but I wanted to ask before I called M$ and spent two hours on the phone with them. Thanks.

>>We are experiencing problems with Illegal Operation errors on several of our PCs use NT Workstation 4.0 w/SP4 and VFP 5.0a w/SP3. They seem to occur randomly, sometimes in design mode, sometimes while running an application. Any suggestions on what might be the cause?
