That's Ok, John, I don't think any less of you :-)

Ok here's the scenario. You have an instance of VFP running. You're in Explorer and double click on a PRG. With Bill's solution it will fire up a new instance of VFP and edit it. If you then click on another PRG in Explorer, it will presumably fire up yet another instance. This is less than ideal, but still pretty slick.

I'm hoping that someone chimes in with the proper DDE message that needs to be used, or perhaps a registry trick.
