I am using CSS3 Pie for doing cross browser border-radius and box-shadows. This works really great. But when used together with the jQuery blockUI plugin (using modal dialogs), CSS3 Pie functionality does not apply to that dialog element.

This is because of the z-index problem with position:fixed , which is also described here. I already tried to change position to relative on the target element, played arround with the z-index, but it won´t work.

Maybe someone of you had a similar problem and can help me out here. Thank you.

(this question was also posted on stackoverflow)

anybody has hints or comments on this?

I'm not sure it's actually a z-index issue, position:fixed should handle z-index fine. Problem is, there's another bug where it doesn't position the element correctly if its target is position:fixed. There's a ticket for it: http://github.com/lojjic/PIE/issues/#issue/74 -- see the forum post linked to in that ticket, it has a patch which seems to fix it in a subset of cases. It might help you get around yours.
