Does this really have anything to do with ProDOS (and 2.5 specifically?)? Does it not repro with earlier versions of ProDOS?

I observed something similar in A2DeskTop (under 2.4.x), but my initial debugging indicated that it was just a fact of life (i.e. hardware/firmware limitation) that you can't detect that a mouse is not present. I would be surprised (pleasantly!) if this somehow ProDOS getting involved.

I'm testing under emulation most of the time where this situation doesn't apply, and it doesn't seem to affect the Apple IIc/Laser mouse behavior. I can set up my IIe but maybe someone else can test before I get around to it?
