Edited the "Disc" property of an album. Files are processed fine and then a "Error Occured" dialog appears:

(Various Logs this evening sent, most recent ID was: 45C326AB)
When I hit "OK" the message is sent to the server, then MM5's window goes completely white and I have to use "End Task" from the Task Manager to kill MM5. The Close "X" and Close menu item (Menu when clicking on the MM5 Logo) don't work.
