Scaleform Buttons under a PNG

[winterdreams]

So I have a UI and I have a grungy texture that is above the UI. The buttons will not work because of the PNG on a layer above. If I move the grunge then it won't have the same appearance, like a digital screen. Any suggestions to make the PNG not register when detection button states?

Thanks

Already fixed, I get so far into Scaleform that I forget my basic as3. Solved!

movieclip.mouseEnabled = false;
movieclip.mouseChildren = false;
