This is the case with the idle handler as well. These are very inefficient and would basically bog down the message path if they traversed the it for every object on every cycle. They probably should be deprecated.

A better mouseWithin would be something like this:

local sMouseWithin = false

on mouseEnter
   put true into sMouseWithin
end mouseEnter

on mouseLeave
   put false into sMouseWithin
end mouseLeave

Or just handle mouseMove instead of mouseWithin.
