I love "repeat while the mouse is down" because it allows me to do a bunch
of mouseDown stuff, then a bunch of mouseUp stuff when the repeat ends, all
in one handler.

I'm working on an HC stack right now that uses it. Never had a problem in
HC, except with the occasional bonk in an idle handler, but NEVER in a
repeat loop.

Does 'grab' and 'mousemove' really have potential response speed problems in
RR/MC? I have some HC stacks I want to convert where a 'hunting' button is
tied to the cursor. This ability is key to the stack's function, no good
without it.
