I had one tab open and then I opened two tabs from the favourites menu and closed them and I got the above message from UR. I exited out of UR and now whenever I start it up, with any of my databases, not just the one that was previously opened, the hourglass displays and I can't do anything with UR apart from shutting it down with Task Manager.

Looks like I'll need to reboot my system again to get UR to recover.
