MSIE problems to watch out for when using animation libraries

I had some issues with one of the code examples for the upcoming book. MSIE has a very annoying bug that when you use an opacity animation – for example with YUI or jQuery: When the element you want to fade in our out has no background colour, MSIE messes up the font for some reason. Another problem is that when you use jQuery for the fading, the element needs to have hasLayout set.
