GetObjectPtr( blah ); is a function that is present in lots of
the sample source code. It's proper use is to get the pointer
of an object, like a control or something, and not a form, from
an objectID. FrmGetObjectPtr is the proper way of getting a
form pointer, also, FrmGetActiveForm( ) will get you the active
form's pointer as well.
