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
