i have been trying to open jgriffin's stand alone profilemanager.app for an embarassingly long time [over a month] with no success. i have downloaded every iteration of the app from the first beta to the stable release. each time i try to open it i get pop up warning saying “a copy of profilemanager is already open. only one copy of profilemanager can be open at a time.” i have combed through the developer’s blog, mozillazine articles and mozilla support for an answer. all to no avail. if anyone has an a solution to this conundrum that they are willing to share, i will be forever in their debt. please be advised that i am a relative newcomer to the internal mysteries of snow leopard when suggesting solutions. thank you.
