Automatic Unchecking for Extensions after closing ArcMap Desktop

Idea created by 1_jennyr on Feb 6, 2012
    It would be nice to have the extensions disengage when closing ArcMap desktop.  We are using concurrent licenses and if I forget to uncheck the extension box when shifting from ArcView concurrent (spatial analyst extension can be used) to ArcInfo concurrent (for sde editing), another person will be locked out of using this extension until I go back into the ArcView concurrent license and uncheck the extension box.
