One of the developers I work with has just launched his new blog. You can read it here (www.merhl.com/webdevblog)
Joe is a Macromedia developer who can write wicked code for Flex, flash, and other macromedia products.
I noticed his blog had the same issue with FireFox. The style sheets (css) will need to have the rendering code added, < ? Header ("Content-type: text/css");?>
