messages to buttons when the mouse is already down

I would like to track the movement of the mouse through an array of 
buttons by hilighting each button that the mouse (button already 
down) passes over. However, the mouseEnter, mouseMove, mouseWithin 
messages are only sent to the first button because that button 
receives the mouseDown event and is the target. Similarly the 
mouseControl function (yes, it took me a couple of tries to notice 
that it was a function and not a message!) only returns the target.

How can I get the other buttons to hilight without requiring the user 
to click each individually?
