VFP 7.0

I have three forms (1) the "Main Menu" form, (2) the "Quote Processing" form, accessed from the "Main Menu" form, and (3) the "Quote Calculator" form accessed from withing the "Quote Processing" form.

When previewing a report (designed in report designer) which I can access from within the "Quote Calculator" from, the report hides behind the "Quote Calculator form", and appears in fron of the "Quote Processing" form.

How may I prevent this, and make the report appear on top of it's owner, being the "Quote Calculator" form?

I have tried several combinations of the ShowWindow property all these forms.
How should I set up these properties for these forms? I only wish one form to be accessed at a time from the main menu. Every child form must be closed before a user can go back to the parent form.

Thanks,

John
