Websites in Asp.Net does not work in Windows Vista

I have a strange question! I have developed a website in asp.net webforms, I've tested this website in IE7, IE8, Ie9 (RC), Firefox, Chrome and Safari, in Windows XP and Windows 7. Everything works fine.

But in Internet E开发者_C百科xplorer in Windows Vista, does not working. The website opens in browser, but when the application needs a postback it does not work. I don't know why it is happening. If someone could suggest something to accomplish this? I appretiate!

Thank you! Att,

Highly doubt it's the OS... Check your internet options...

A failed postback could be due to a javascript error. Have you tried using the Javascript console (Shift+F12) in IE8, or using Firebug Lite in versions lower than IE8? Could you turn off surpressing javascript error notifications to see if this presents the issue?
