Setting focus back to the Powerpoint Application

[FProject]

Hi,

My add-in has a toolbar button that opens a form with some options,
the problem is that working with this form takes all the focus - i want to be able to go back and work with the presentation itself but unill the fom is loaded -it is not posibe.
I want the focus on the pesentation while he form is still loaded

Any idias?
