I dunno, I think it's everything. This kind of thing is typical of Microsoft -- they just don't care about anything because they know they'll be making money anyway.<p>IE is a tool to leverage their monopoly and kill competition. It's _supposed_ to be a PITA so that people dedicate all their time to IE and its competitors get left out in the cold (meaning that you must have Windows to use the websites you want to use).<p>They just don't care about quality and they're not even a little bit apologetic about it. I'm willing to bet there are thousands of known, serious IE bugs within Microsoft, and the bosses won't let anyone fix them because the bosses don't have any reason to fix them.
