I'm hoping to implement a technique for corners I found in a book called CSS Mastery. The book uses a method for adding transparent corners via JavaScript and CSS that is from Berea Street http://www.456bereastreet.com/archiv...s_and_borders/

It seems that IE7 wants to throw out the bottom corner in all my tests by allowing the left border to show behind the bottom left corner. This happens on my own tests and on the examples from the authors web site.

My tests:

Author Example 2:

Anyone else seen this or found a way to work around it or have a good suggestion for a replacement technique using transparent png images?
