Problems with creating behaviors using transparent images imported from Photoshop.

I have been trying to create behaviors using images imported from Photoshop. Many of these images have a transparancy. I am using a Tap behavior to "show" a transparancy over another image to highlight it followed by "hide". Some of these work during preview mode, but some do not even though I use the exact same settings. Then, when I "share" the highlights are working, but are showing up behind the image not in front where they should. I have things layered in Aero so certain things should be on top, but it doesn't seem to matter... Please advise. FYI, I am using the desktop software to create.
