Whilst recently downgrading to check my sites in IE6 I have come across a few serious issues on my web directory. http://www.fruitydirectory.com/ - The blog posts/articles under the categories won't float in the right places. - The header/navbar is messed - Transparent png images, such as the trees and the category icons are not transparent in IE6. The site works OK in FireFox and IE7. Can anyone help? I'll donate a small amount of money to those that can.
IE6 is one of the WORST browsers ever, you will have to use a bunch of IE specific hacks in your CSS code but if you're interested I will offer my assistance. PM me if you would like my help.
