Internet Explorer 8, CSS fixes and hacks / IE8 bugfixes

Today, Microsoft released their Internet Explorer 8 BETA.
If you have problems rendering your websites in IE8, or have come up with solutions/hacks to fix CSS bugs found in Internet Explorer 8, feel free to post them here and share your solutions and bugfixes for Internet Explorer 8 with the rest of the webdeveloping community.

IE8 is known to pass the acid 2 test, unlike any other browser to date, so it should save web developers a whole lot of troubles getting their website to display right in each browser.
Now all they need to do is find a way to get users to update their browser, I know some crazy/dumb people who are still on IE6 and refuse to update. A method to do this would be to make this little yellow balloon thingy pop up in their taskbar and notify the user to update every 5 minutes. Eventually this will drive the user nuts and they will give in and update their browser. Mission complete!

For anyone interested, you can download the beta here.
