Description Dejan Glozic CLA 2001-10-10 21:39:53 EDT 
I found these exceptions about half an hour after they were thrown. 
I might've been using self-hosting when they occured. ( not sure though because it was around the borderline where
I switched from non-self hosting to self hosting.

NOTES:

JohnA (7/30/2001 10:19:36 AM)
	Appears to be a problem with the PDE editor's notification listener.  Updates should be async'ed to run in
	UI thread.  Moving to ITPPDE
