chrome

Hi, This works great with ie, but in chrome it seems to be competing with css, and I get a black background (when i don't want it) on the upper/lower border area. I see it is showing up in the element.style has a background-color: rgb(0, 0, 0). If i remove curveycorners, css works fine on chrome, with it on, background shows up.

Is there something I can do to hide curveycorners from chrome?
