Sorry - I was unable to reproduce the problem, and don't know why. I was just happy to move forward!

Here's the scenario: I'm running VFP 6.0 SP3 (the developer's version, not a compiled vfp app) on a Windows 98 machine connected to a network served by WINNT 4.0 I issue the following set of commands from the command window:

>>>This sounds like the Optimistic lock issue - it requires a registry hack at the server end to disable optimistic locking; under Win2K Server, the hack is:

And when you look at the open files list on the server, it says that I still have the table open.
