Be careful with this. We've used it on a number of sites, and whilst overall it's beneficial, there are a number of weird things to watch out for.

For instance:

  - Don't add rounded corners to a <table> element - this will crash at least IE7 on XP
  - Don't try to rounded corners an element you've hidden with the "left offset" technique (position: absolute; left: -9999px;). This will crash at least IE7 on XP.

I think there a few others I have since erased from my brain due to IE-induced PTSD. YMMV.

I'm submitting this again, even though it already got lost in the "new" queue once (http://news.ycombinator.com/item?id=1736030) because it's an amazing solution to a common problem. It helped me tremendously and mentioning it in another thread seemed to have helped others (http://news.ycombinator.com/item?id=2085671).

I think this works great in some situations however on a site I was working on it fell down when zooming the page and ended up having to revert to the usual image based rounded-corners.

Thank you

66kb of JS (compressed) is a bit much, this should be broken down piece meal so you can do JUST rounded corners, drop shadow, etc. Would be much more useful that way (rounded corners I'd imagine account for vast majority of the use cases). Cool though.

I've tried to use this in the not-so-distant past, but unfortunately it introduced all kinds of weird rendering bugs to the site. I hope others have better luck.

What kind of black magic voodoo is:

   behavior: url(PIE.htc);

Javascript-y?

Haven't quite digested it yet but it seems to be microsoft's attempt at a component model for html/javascript/css.
