I'm having a problem getting the images in a sliced table to butt together properly. The problem occurs in IE 4 & 5 and NN6. (It's actually working properly in NN4 for once!)

There is a gap just under each rounded corner at the top left and right, causing the purple bkgd to show. I've tried everything I know to do. Any help would be appreciated.

Thanks!
