target(), mouseControl(), etc. when mouse button is down

[Trevor DeVore]

What is the best way to find out which control the mouse is over when 
the mouse button is depressed?  Functions such as target() within a 
mouseMove handler and mouseControl() placed in the group script always 
return the control the user clicked on rather than the control the 
mouse is currently over.

I have a scenario where I have a series of buttons grouped together.  
If a user clicks on one of the buttons and moves over another button 
with the mouse button still depressed then I want to shift focus to 
that button.  I haven't fond an efficient way of shifting focus since 
it is difficult to find out when the user moves over different controls 
with the mouse button down.
