>It seems that at a particular client's site, when running on an NT netowrk, that after they exit our VFP 6 application, the network is still holding on to the files. No other user can get exclusive use of those files unless they close them through the network. Why is this happening and what can be done to avoid this?

There was a big, long thread recently on this. I don't know if it was ever really solved, but it may help to read through it...
