Cool .. I actually could see this from your jpgs too ... Apparently there's a deadlock trying to retrieve the value of your wendy flags at the same time as synchronizing (both methods are blocking on the same object). Is it possible you have Wendy flags as a column in the right-hand pane (the playlist table view)? Try removing that column and see if it still locks ... I'll try to fix the locking tonight so you can have that column on.

Thanks a lot for getting those stack traces ...
