Comment 1 Jared Burns CLA 2005-02-10 17:11:00 EST 
The exception has continued to occur everytime I save a file, even though I've
closed the Problems view. Is the view leaking some kind of listener? Why is it
still causing this exception after it's been closed?
Comment 2 Dirk Baeumer CLA 2005-02-11 04:04:56 EST 
Martin, got this fixed by fixing bug 84747.
Comment 3 Martin Aeschlimann CLA 2005-02-11 04:26:08 EST
