I have a working DockWindow Add-in for ArcGIS Explorer. This Add-in shows a form that the user interacts with and selects options. When the Explorer application is shut down and then restarted, the form is still open and appears if the user had it open in their previous map. In other words if the user has the Add-in showing, and doesn't close the dialog themselves before shutting down the application, it will show by default the next time they launch Explorer. This appears to be the default behavior with Add-ins.
Is there a way to force the form to close when the application or map document is closed? I don't want the form ever to show when the map first loads.
Thanks
