>I tried your suggestion, and I didn't even get to the debugger. As soon as I click on the Find button, it errors. I do know that the oCallingForm property at that point is a .null., but that's about it. I have looked again at the devguide to be sure I haven't missed anything, and as far as I can tell, all is OK. Should I just start over?

I'd try Rox's suggestion of recompiling all first. Then I'd remove the code from the Init() of the find form, since you're not even getting that far. In the Find button, Click() method put:

SET STEP ON
DODEFAULT()

Then trace it through.
