RDM not responsive when it can't reach host

If a destination server is down, or the Internet connection is very horrible to that customer site (i.e. intermittant) Remote Desktop Manager becomes completely unresponsive as a whole app while it tries/retries to reach that one connection. This of course ties up all the other sessions and any other capability in the app. Is there a way to isolate sessions so that if this is happening to one session it doesn't hamstring all the others, and the app as well?
EDIT: To clarify... looks like it's mostly when RDM's trying to reconnect to a connection that is no longer available, as opposed to initiating a connection to a dead host.
