I haven't seen this, working with some very large tables, with both NT Server and NT Workstation. But, then, I didn't have the problem with VFP 5.0a; if you're talking about the message that VFP is not responsing when running a single, processor-intensive, command (such as very complex SQL Selects) then yes, but the problem comes from the fact that VFP doesn't respond to Windows events within the context of a single, atomic step - if you have a SQL Select that takes 10 minutes to run, other events don't get responded to, such as timer firings, or standard Windows messages. But that is not a memory issue, and it is not limited to NT.
