I'll check out multi connect, though my use case would be a single connect one (making applications for a single desktop user), so I would need to make a multi connect act like a singleton (I can do this though), but that does feel weird to me.  I chose singleton because it fits what I need at a glance.  

The main thing is if I close the browser window, then in my code Gnoga.Application.Singleton.Message_Loop still hangs as if it is waiting.  I assume because Gnoga.Application.Singleton.End_Application isn't called, but I have not found a way to figure out "when" to call that since I don't have a way of telling when the browser closes or navigates to a different page.  I did not check multi connect but I can play with that as well and see, though I would have assumed Connection.Hold acted the same way as Gnoga.Application.Singleton.Message_Loop in terms of how it locked/unlocked.

I definitely will look at multiconnect for some projects I have, but I still want to make sure I have some applications for my coworkers to use in our lab (configure some devices).  I just have to make sure they aren't having to do stuff at the command prompt if I can avoid it.
