    I am having a strange problem that I can reproduce.  I have a Windows 2008 R2 server with the default Document setup to bring up the default.aspx page.  I am running the latest build of the Telerik controls.

    On my default.aspx page all I have on the page is the RadScriptManager, RadAjaxLoadingPanel, RadAjaxPanel and a asp button inside the RadAjaxPanel.  The RadAjaxPanel is set with the LoadingPanelID of the RadAjaxLoadingPanel.

    On the button click event I have System.Threading.Thread.Sleep(5000) this is to just have the loading panel display the loading image just to make a simple test.

    This all works just if I call the http://sitename/default.aspx page, but if I just call the http://sitename and have the server load the default document “default.aspx “ the loading panel will not function and display the image.  The problem only occurs on Windows server 2008 R2.  I do not have the problem on Windows server 2008 or Windows 7.

    I have contacted Telerik support and they have basically told me this is my problem, even though I have recreated this on 3 different Windows 2008 R2 servers and 2 different projects.  So I guess I am just wondering if any of you have seen this problem or you could test this and see if this is really just me. 

    Thanks for any help
