Hi Jeff,

Your are able to use a collection of forms object reference.

So when the user hit a form menu

You check in the collection.

If a form instance exist it is easy to bring the form on top otherwise you are able to run the form for the fisrt time.

The check can also be done in the init code of the form and scan a VFP collection. ( I don't know if it is possible to use the Controls array in a form to locate children forms ? )
