Hi Ronnie,
AFAIK, if any of the event handlers calls event.stopPropagation() or event.stopImmediatePropagation(), it does not bubble up further. Other Flexcoders can correct me if I'm wrong :-) Regards, Swaroop _____ Just want to understand if the main application class receives mouse event at all? Would like to understand why doesn't the mouse event get bubble up to the main class cheers, Ronnie
