    Through very much trial and error I have discovered a repeatable issue/bug with the RadTreeView inside of a RadWindow.  This issue occurs in IE9 and the latest Chrome, I have not tried FireFox yet.

    Version of Telerik.Web.UI is 2012.2.607.35

    When placing a RadTreeView inside of a RadWindow's ContentTemplate, if any of the RadTreeNodes text property contains the character sequence "trial" the contents of the RadWindow are displayed at the bottom of the page.  After clicking the RadWindow's OpenerElement, the contents disappear from the bottom of the page and appear correctly inside the RadWindow.

    Simply change any of the nodes text property to something that does not contain the word "trial" everything works properly.  I am including simple code blocks below that should reproduce the problem.  Note that there is a PopulateNodes() subroutine in the code-behind page; this issue occurs when adding nodes to the RadTreeView programmatically as well.

    Please help with this very bizarre bug.  I am happy to provide any additional information you need to reproduce this problem.

    I was able to replicate the issue under the telerik version 2012.2.607.35. I tried to replicate the issue in the latest version but no avail. Please try updating to the latest version of telerik controls.

    Hope this helps.
