 I would also check the mirror around the back which seals the film from light 
leaks.

 I have noticed a similar problem to this in one of my bodies.  It actually does 
get bad focus indication occasionally when resetting the mirror lockup.  The 
mirror sometimes "sticks" halfway down (so I don't think it's due to the 
foam).  It "clicks" back down after a couple of seconds (or if I flip the mirror 
up and back down).  It also has a minor focussing problem in addition to this 
(either the mirror or the screen is sitting unstraight).  I'll be getting it looked 
at when I get around to finishing the film that's in it.

 I wonder if that was what was causing random light leaks in one of the 
bodies I recently sold.  I was suspecting the foam in the back but it was so 
intermittent I didn't bother trying to get it fixed.

 Well if you don't press the black button you can't change the asa setting :)

 Yes, and the viewfinder is the best I've ever looked through.  I just wish it 
was removable so I could fit a waist-level finder.  I also love the light meter 
although I do wish my repair agents could competently service/calibrate it.

 Thanks for the information though; I'll be filing this one away for future 
reference.

Cheers,
