I'm always learning new things about how crap IE really is.
It's amazing to see how a company can take something so beautiful (Web Standards) ... and twist them around to suit their own aggenda. Thanks Microsoft. I just uploaded a new module to one of my clients sites and to my dismay, it wouldn't work when I was demo'ing it for them. I do all my development work in firefox and usually test everything in IE before I publish it, but this time alas I didn't. Shame on me. :( Anyhow, the problem occurred in an image upload process where the file type is restricted to image/jpg,image/jpeg,image/png .. that would work in the real world, but not in the Microsoft world. It seems they've invented a new mime type. image/pjpeg.... that's right. What the @$@# is a pjpeg?

Progressive Jpeg? kind of annoying that they can't stick with standards!
pjpeg.... been down that road. Took me a few cycles to figure it out. Client had problems, I didn't until he emailed me his jpg file.... LAME.
Interesting... hadn't heard of this before. Wikipedia didn't seem to have it, but confirmation of "progressive jpeg" is here:

I haven't researched the issue, but I think it makes sense to have a separate identification when sending a JPEG-compressed image in other than row-by-row order... otherwise you might have a simple JPEG renderer balk when it tries to render a file it can't.
Microsoft *did* introduce some things before the W3C consortium documented its acceptance, like XmlHttpRequest and OBJECT and DIV, but in this case I think it may be a multiple-renderer problem where some (FF) accept liberally and some (IE) accept conservatively...?
Jason,
You can't blame MS for that one. Credit for that goes to our wonderful US Patent Office. Adobe has already published guidance on getting around it if you search through the knowledge base.
Tell me about it. I've just learn too that in the latest update for IE, all embeded objects, flash, java applets, etc have to be click on to be activated. When will the madness end?
