Tom,

I think you're running into a timing issue. Referencing "ThisForm" before the form has completely Init'd can cause some "weird" anomalies such as you're seeing.

Try reversing your code as follows:

LPARAMETERS toCallingForm

IF !DODEFAULT()
   RETURN .F.
ELSE
   ThisForm.oCallingForm = toCallingForm
ENDIF

Hope that works!
