If I use round corners, borders and box shadow(not inset) on a container it all works fine in IE7 &8 but the continer has its background colour filled with the colour of the box shadow.
If I comment out the box shadow css line the problem disappears.
I have position: relative in the css.
I want to have a full background image in the body tag show through containers on the page so I do not want to give containers a background colour at all.
Does any one know of a solution please.

This is not possible right now. See https://github.com/lojjic/PIE/issues/12
