I am attempting to do my jumplists with a "seamless" semi trans look and I've run into a couple of issues.
Here are the 3 images that make up the section.
Frame

Center top

Center Bottom

These 3 images are 90% opaque.
Here's the problem. When I apply the blind the center part isn't transparent. It shows up as solid. Only after cycling through a couple of jumplists will transparency be applied. It's important to note that the trans effect will only apply if I open several jumplists with a history list (like an explorer window with a list of recently opened docs)
See example

Notice also that the bottom and right side of the list aren't being blurred like the rest of the panel.
My question is: am I doing something wrong or is what I'm attempting to do impossible?
Also while we are on jumplists, why are there text margin, font, and color setting for this section when they have no effect?
