Hey Barb
My experience with is that you don't need to release a modal form for program execution to
continue in the code that called the modal form:

oMyForm=CREATEOBJECT('MySpecialForm')
oMyForm.Show(1)
*-- These lines will execute after the Modal form has been hiden with a
*-- Thisform.Hide() if Show(0) was used these lines would execute
*-- imeadietly after the form was created.

lcWhatIWasLokkingFor=oMyForm.SomeObject.Value
oMyForm = .NULL.
