One last (?) item regarding mouse polling I thought I'd toss out there is the fact that historically polling for the mouse state (down/up) was unreliable. MetaCard would sometimes miss when the mouse state changed, which could wreak havok with scripts that relied on this state change to terminate. I ran into this early on when switching from SuperCard to MetaCard, and it was then that Raney explained the use of mouseMove with mouseUp/Down handlers that set variable states, and specifically to avoid polling the mouse state.
Perhaps things are different now, but I guess fear of old behavior still makes me leary of using mouse state polling.
