If you are simply calling the goApp variable then your child object is not specifically binding to the parent, are you actually referencing the goApp variable from a property from within the timer?

2-way association doesn't go down well at all in VFP, if you can avoid it, then I would strongly advise it, otherwise you end up having to release the child object from the parent, from the child.
