CSS3PIE - how trouble free is it for IE6 - IE8

I'm wondering if folks can tell me how trouble free CSS3PIE is for IE6 - IE8 (beyond the known issues). It seems like an excellent addition to allow one to use CSS3 features -- rounded corners, gradients, shadows, etc -- I 开发者_如何转开发just have limited time to invest into investigating stability / errors.

Thanks

P.S. Does it turn off automatically in browsers that support CSS3?

It has worked perfectly for me and it only affects IE so you dont have to worry about the other browsers.

Don't worry it's transparent. The only "real" problem I've been having was with opacity transitions in ie8 : In order to make a div fade out, you need to apply this css definition to every child element :

filter: inherit

Problem is it doesn't seem to work on the shape elements css3pie generates with css only. I had to modify the minified .htc file as folows : look for the second occurance of "shape" in the script. It's in a function called 'Aa'. After this statement:

g=e[a]=f.p.Za("shape");

you can add:

g.style.filter="inherit";

This clearly is a hack but it works great! It is just for IE8. IE7 deals with transparency differently (http://www.jacklmoore.com/notes/ie-opacity-inheritance)
