There isn’t a serious standards-focused web developer on the planet who hasn’t had irritating troubles with Internet Explorer. We’ve finally reached a point where IE on the Mac is largely irrelevant thanks to Safari and Firefox. Versions of IE on Windows older than 6 are also marginalized for the most part. However, even though IE6 offers decent standards support, it is filled with behavior from the bizarre to the downright idiotic (and everything in between, of course). I could list dozens upon dozens of these issues, and such bugs as “double margin” and “peek-a-boo” are just two well-named examples.
