>When do you get Dr Watsons? Randomly, or consistently at one point or other in your program? VFP itself, or in your app?

As I said, it's consistently, when I try to load one form from the command box. The same form runs compiled, and can be called form 2 other forms, although not from a third. All other forms checked run OK

>Do the scxs live on your machine or on the network? NT Server?

It's a standalone NT4 workstation. No network.

>Are you calling the forms with the same syntax?

Yes: Do Form xxx for all forms tested.

Thanks,
