I don't know if it is the best place to post that message, but the rendering of a web page with a table which width is 100% is awful. The width of the web page is then huge. I have to scroll right to see the content of the table.
As example you can try http://www.javasoft.com
I am using K-Meleon 0.4 Build 301.
BTW it works on XP Pro Beta 2.
