Bug 3883

Okay, this might be a claws issue, it might be a window manager
issue (xfce4), but I don't see it in any other application.

I have claws mail set to auto-start with my desktop session, but
while I can read (and either via menu or control-o) move emails
between folders, "drag and drop" moving of emails doesn't work.
(you drag to destination, but it 'snaps back' and doesn't move).

Close claws and restart (in the same session) and it's works fine.

So it looks like some sort of interaction between xfce4 starting 
up and claws starting up. Annoying, but tolerable. Has anyone
else seen this?
