I think this is a permissions issue. I'm now seeing dbs on one of my hosts. However, that host now has a red lock on it in the Instance view under the Resources tab. And when I change the view to Database, it no longer shows the DBs on that server. It *does* show the DBs for one of the hosts that I recently added.
Clicking "refresh resources" on the Resources/Instance view just gives a spinning "updating information" bug in mid-screen.
Also weird: my Dashboard shows 3 hosts "up" on the SQL Plug-Ins screen, but only two Instances are showing under Resources.
I'm using accounts with inherited full SQL rights on the hosts. Do I need to establish explicit rights for each login on the hosts?
