In IE 8 we experience problems with the image and document manager. We cannot browse or upload files. All other browser (including IE7) are working correctly.

We tried the meta tag <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /> to solve this problem without success. Can anyone please help me solve this problem?

Below the exception:

"Webpage error details

Hi,

You are using an older version of RadControls for ASP.NET AJAX released before the official release of Internet Explorer 8.  We provided full support for IE8 in Q1 2009 SP1 (version 2009.1.402)  and our recommendation is to upgrade to the latest build 2009.3.1314 in order to solve the problem.

Kind regards,
