CSS3 problem in IE9 when running with Xampp?

[pereira]

I'm having some problem with xampp with Internet explorer 9 installed on windows 7 32bit. The IE 9 does not display some CSS 3 code properly (such as border-radius) while running through localhost. The CSS works fine with other browsers on localhost but not only with IE 9. However, the code works fine with IE 9 if i open the html file without xampp, (just by double clicking on, so that it has some path like (C:\xampp\htdocs\test\x\index.html), which means there is no problem with CSS or IE9, but it does not work with xampp. Can someone please tell how to fix it? Thanks.

We can't because wie don't know your script.
The Apache http daemon just serves your pages.
What should be different to that (exept of wrong paths)?
