Got the problem yesterday, after some investigating:
- senders of Project >> spawnNewProcessIfThisIsUI: suspendedProcess
usually do not suspend the suspendedProcess parameter until later in
the methods. (most of these are Debugger opening methods)
It seems to me that for a short time in these methods, 2 UI processes
can actually be active (But telling the same world to update).
Thus, if one exits MouseOverHandler >> processMouseOver: while the
other is in it (which resets leftMorphs to nil), could cause the
described case to happen.
Would be nice if someone familiar with Squeak threading model could
confirm/disprove my theory :)
Cheers,
Henry

Which, of course, doesn't get to the bottom of the original problem.
That being, why there would be multiple processes (rather than just
UI process) modifying any Morph state...

Yes, I think that would be best.
