Unhandled exception

I got the following exception using the released version:

************** Exception Text **************

Here are the steps I took before getting the above:

1. Compared two databases.
2. Droped and rebuilt one of the databases while the app was up.
3. Hit the refresh button, but got a message that could not connect to one of the databases (as I later found password field for the rebuilt database was empty).
4. Pressed 'Ok' and got the exception.

Thanks.
