BoundryPolygon: does it work?

[ger]

In an effort to squeeze the new self effects icon indormation into my player windows without having to make them any better I hit on an idea for how to condense the concentration display. Problem is, in order to do it I have to overlap all 5 indicators—I had thought that by using mostly transparent images and BoundryPolygon settings I could make all 5 distint to a mouseover even though they're really stacked atop one another, but it doesn't seem to work. Any suggestions? (XML & DDS attached below)
