Alex is, of course, correct. Listening for MouseEvent.CLICK on your TabNav in the capture phase and calling event.stopImmediatePropagation() in the handler will prevent switching to the new tab. (mouseDown didn't seem to work) One thing to remember though is that since you're listening to the capture phase your handler will get called twice for each click. Once during capture phase and again in the bubble phase.
