For one of my Toolbar add-in to ProcessBook I need to count the number of open ProcessBook Dispalys. But I don’t see an "on ProcessBook close" event which is causing me problems when users close a screen. At this point I have a way doing it so it counts properly except for when the last display is closed. I have tried "before display close" but that does not work as the display is still open. I was wondering if there was an events like display close.
