I also use a signal instead of a message so that I might not call
WhichLayer() for every mouse movement.  

Well, if you start getting deadlocks, you might throw in an
AttemptSemaphore() on the SignalSemaphore inside the LayerInfo before
calling WhichLayer().   (Simulating a call "AttemptLockLayerInfo()".)

Note, by the way, that one good test for Sun-style window activation is
the Workbench rename window/gadget.  AutoPoint2 (commodities example)
passes this one, but I don't use it, so I might have missed other 
pathologies.

More or less, eh?

Well, if it really is All-in-one, and until Commodities is a little
lighter on its feet, you might be right.  It's point is to have only
one Input Handler around for multiple applications, with user-interface
standardization and ease of application development right up there with
"load."

I don't think All-in-one is going to be true for other people.  I already
have plans for input thieves that aren't appropriate for being
always loaded (like my hostile picture snipper).  Priority between
key translators and hotkey programs is also a thorny problem.

Anyway, I never fault anyone for carving their own development environment.
