For the last few days I have had trouble moving emails into folders. They move, but leave the original behind, giving the impression that the move has not been successful. Except that if I close the main window and open a new one, the original email is no longer visible. It has moved successfully. I have tried drag and drop and have also tried Move from the Message menu. The same happens with deleting emails. So the main window does not seem to refresh properly. This is annoyingly intermittent. Anyone have a similar problem?
