Hi Gary!

	I've aready tried a hack like:

	(leftMorphs isNil or:[overMorphs isNil]) ifTrue: [^nil]. "handle
non-synced error case"

	and is not enough. Is very strange because happen sometimes I catch of
this dnus and #leftMorphs and/or #overMorphs are nil but it is after the
injected isNil control. Like it happening to be modified from another process
while executing just those lines.

	I confirm you about eCompletion. I'm using it, is very important to
icrease usability. My actual workarround was to use the more processes/debugs
stressed image without your enhancements and use it in the other images with
smaller chance of getting stressed.

	Most probably event handlers aren't properly unsubscribed and certainly
they are not a null idempotent when they are in an invalid state. I don't
evidence of your enhanced events envolved on this but is certainly not happening
in the non enhanced images (which also have ecompletion, shout and others).

	cheers,

Sebastian Sastre
