I have a TabStrip and MultiPage with the content of the pageview's using ContentURL. I'm also adjusting the height of the Multipage to be the height of the Content via document.documentElement.clientWidth. If I open the page in the browser IE10 or Chrome, it appears to be working fine, however if I open the page in a RadWindow the clientHeight excludes the height of the TabStrip.
This appears to be an issue related to IE10.
