[flexcoders] Is there a way to detect mouse button state without tracking events?

[Dave Kong]

I need to find out at this particular moment, if the mouse button is up or down.

Trying to work around the issue with wmode=transparent in FF. If I scroll a 
list, and drags cursor outside of the player and then releases the button. That 
mouseUp event is never captured by Flash Player, so when I move mouse cursor 
back, buttonDown is always true for all mouse events.  So I need a workaround 
on moues re-entry to detect if button is truly down, if not, call the 
scrollThumb's releaseButton function so it won't keep on scrolling.

Thanks!
