>Actually, no, I cannot do that. I am talking about opening forms that each need to be individual items. In other words, I have a tool where the user can enter parameters and get back some data. The user may want to compare data from two _different_ sets of parameters. Instead of having multiple parameter areas on one form, I figured, why not just let the user instantiate another form and place them side by side? If I just always bring the original to the forefront this is impossible. Then they can open 2, 5, or 65 screens at once. Therein lies the struggle in this app...almost everything is non-modal, and things can be opened up multiple times. I have most everything under control, and with some recent postings, I think I have a way of doing this public form stuff too.

I understood what you do, and it was exactly the reason why I asked. It's reasonable to give user two (maybe three) instances, but 65? It might be better to limit this number, just ask your users what actual number of forms they want to see on their desktop at the same time. I believe that ultimately, you will need in just one form instance with some mechanism in form.activate event to bring up the last result for current activation.
