I have a fairly large VFP EXE on the network and the users actually run a copy from their local workstation.

It is a little slow to load (not too bad) so occasionally users click it AGAIN thinking it did not load the first time.

I do not think it actually hurts anything, but I would prefer that the user NOT be running two copies on the workstation at same time.

How can I Prevent Running two copies on same Work station?
