Not particulary. Pressed the Reply button instead of Reply all. Fixed.

As you noted, they are ugly artifacts when the the border-radius is too 
on a part, and great on the other part. A designer may want a square radius
as it's more beautiful.

You may argue that the problems may be solved using antialiasing, but even
with that, you will continue to notice problems.

Personnaly, I would love to have a way to have the 100% unit to have the 
value as min(width, height). It can help me to make a circle radius border 
grows as the box I use grows.

Imagine the case of a [25% * 2000px] box that would be the main content of
my page. If I want the rounded border to be in function of the width of the 
I must use a % unit. But if the result DIV is 250px * 2000px, your behaviour 
result into a not so beautiful radius. The solution used by FireFox would 
a better result, to my opinion.

Try it with a 1% border radius. Your solution would create a 3*20px border 
while the FireFox solution produces what I intended : a 3*3px border radius.

Would it be so bad having a (facultative) keyword that specify whether to 
use one
or the other solution to compute the % unit ?
