curved css corners for some reason dont seem to work in IE9. I know it supports it however i have looked all over the web for a solution and cant find one that works for me.
I found if your using the CSS style filter
for IE8 and below browsers it will interfere with IE9 styles causing border-radius
to not work and possible other ill effects.
To fix it add this to your html head:
<!--[if gte IE 9]>
<style type="text/css">.elementClass { filter: none !important; }</style>
<![endif]-->'
Looks like the page is firing Quirks Mode, try moving those script & css includes down inside the tag... nothing should ever come between a doctype and it's html tag.

I found that my border radius in ie9 is working on localhost but not on a server. Im using css3PIE to acomidate ie8 and below, would this be interfering with ie9?
Use the vendor extensions, -moz-border-radius:15px; -ms-border-radius:15px; -o-border-radius:15px; -webkit-border-radius:15px; border-radius:15px;
You really only need the -ms
version for what you want, but if you include them all you provide a broader spectrum of coverage.
IE9 don't need any prefix for border-radius
(for sure you don't need -ms-
prefix at least for this property!). Your browser probably have a problem. Maybe you're running beta or something like that.
Please test this demo in another IE9 running computer or have your IE restarted and try it to see IE9 renders border-radius
just fine.
Quirks mode is where IE9 switches back to IE5 functionality (added following link to @seanmetzgar post also)
Detail explanation here Investigating Document Mode Issues
With a site I look after, which had ASP code right at the top of page, I added
<!DOCTYPE html>
just in front of the tag, below the code, and IE9 stopped going into Quirks Mode.
