It's official. I had to add Internet Explorer 8 to my list of browsers to support. Curse you, IE 8!!!
How come every version of Internet Explorer that comes out insists on rendering a webpage slightly different from all its earlier incarnations? I look at the same webpage in IE 6, 7 and 8 and one has a weird gap between two elements, one thinks it's Picasso and skews an image, and the third one decides to get creative positioning an element.
I know it's possible to be consistent; Firefox has managed to do it right the past three or four versions I've used. In Firefox, I've only seen one problem that occurred from upgrading to a new version, and that was a fairly esoteric mouse dragging issue.
