>From 3.9a #6520 installed 13 updates taking me to #6533, clicked on a
test case in the list on test runner and got the walkback included
below.  I think the problem may be with Change Set:	6534	SUnit-md.22
which made the following change to runButtonState
	^ running
	^ running isNil
When I revert this one message it runs okay
CS is attached
