When my application is run in a network environment, changes to the data made by machine A are not reflected on machine B until either the database is closed or the user restarts the program. The problem appears to be a caching problem on the client machine in which VFP never requerys the network data. The data is tables optimistically table buffered in private data sessions. Why won't VFP requery the data. I was sure this worked in version 5 of VFP.
