Deluge unresponsive to just about every action

[Brovig]

I have Deluge 1.3.6 running on a local Windows 7 system, along with a daemon on a remote system. It's been working perfectly well until today. Now I'm not able to do just about anything, including: remove a torrent, Move storage, edit tracker, update tracker. And if I click on any of the list of trackers in the left-most column, it doesn't respond to that request. It's just about dead.

Any thoughts on what could be causing this?

I have uninstalled and re-installed the application.

How's the CPU usage on your daemon machine?

CPU usage is really low on the daemon machine... But I still can't do anything from Deluge...

I've also noticed that even selecting Preferences doesn't result in any action either! About the only thing that's responsive is the Connection Manager.

I've concluded that the problem is most probably with the daemon server. Am investigating that now.
