Under which browser do you experience the problem with version 2009.3?
Note that we provided official support for IE8 in version Q1 2009 SP1 (version 2009.1.402)
and if you are using a newer browser you should render the page in IE8 or IE7 mode using one of the following meta tags:
<meta http-equiv="X-UA-Compatible" content="IE=7" />
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />
All the best,
the Telerik team
