How to stop mouse wheel from changing HSlider value?

Question

I create a HSlider to control the transparecy of a map layer.  The Slider works, but everytime after I release the thumb, if I don't click on the map and go ahead to scroll the mouse wheel, it will change the transparency value immediately.  I have to click on somewhere else first, then I can zoom in or zoom out without changing the HSlider value.  Is there any parmater that I can stop mouse wheel from changing HSlider value? Thanks!

On your slider, try set the mouseFocusEnabled property to false
like: <s:HSlider id="slider" mouseFocusEnabled="false" .............../>

I had a problem just like yours that I solved this way...
