This is the first time I've seen this "feature" and it went away when
re-started TB, but I wonder if other people have seen this. Basically
when I right click on a message, the drop down menu item for
Move to "whatever" Again gets greyed out and doesn't work. I
can still move to that folder under the recent folders list and
the greyed out item is updated to show the most recently used
folder - it just stays greyed out until I re-start TB.
