IE6 position: absolute + bottom negative problem

Hi!

I'm expecting some problems with position: absolute in IE6.
Here is the style sheet:
http://wp-themes.depi.sk/wp-content/themes/theme-004/style.css
And here is the page: http://wp-themes.depi.sk/?p=1#comments

The problem is with the comments tip, which has an position: absolute
and bottom: -19px to be shifted down a little.

Do you have any ideas? Is there any bug in IE6?

Thanks

 

Okay, I've solved it myself

Adding height: 1% to the container box solved the IE6 problems.
