I doubt IE7 supports HTML5 or CSS3 etc, or if it does, then just not fully enough, EA is designed to work best on the latest browsers.
There is no dobt about it IE 7 doesn't support HTML 5 at all. IE 8 is not great and neither is 9. You can upgrade the browser to 10 only if you're on Vista, 7, or 8 operating system. Microsoft won't let later versions of IE work on XP. You will have to upgrade to Chrome of Firefox. My question is why are you still trying to use IE 7 there is nearly next to anyone using it. The latest stats show less than 1 %.
Thanks for the reply and the info. Just to be clear, I'm not using XP, I was testing the site on different browsers and operating systems at work and noticed that it didn't load on older systems. Since the stats show such a low percentage of people using these older systems, I guess I won't worry about it. Thanks! BTW, I'm new to designing with adobe products (really all products), can't get enough of this stuff. I'm sure you'll see me again posting some ridiculous question.
IE 10 while better at HTML 5 still isn't that great at it. You can do somethings with older broswer to help the understand some of the things as well. Place this code in the <head> </head> section of your html page
<!--[if lte IE 8]>
this will help with older versions of IE
Animate only supports Animated content in modern browsers. IE <8 doesn't have the capability to handle some of the newer HTML languages. We do have an option to display a static poster image for older browsers and you can add links to different images.
Check out the poster/downlevel options which is what users will see on browsers that don't support CSS3.
You can also use Chrome Frame as an option to display animated content on older versions of IE. You can find this in the publish settings.
