So I have my designer customize a popular Wordpress theme for my new blog at
http://JimGunn.com and although it looks beautiful in Firefox, the flash animation doesn't match the background in the header in IE 6 like it does in Firefox, and the footer somehow ends up at the bottom of the right panel under my bottommost widget. I also noticed a few other Wordpress themes I tried before this didn't work in IE 6.0 at all, according to the designers notes and my installation.
Used to be years ago that sites of various designs look right in IE but not so much in Mozilla or Opera, now it is the opposite! Hopefully my designer can fix these little quirks somehow!
