RadWindowManager in a RadWindow errors in IE10

[Dan Lehmann]

Hello,
Can someone from telerik please confirm this bug?

A few users have identified a reproducable bug with RadWindows inside RadWindows. Please see this thread for the details:

Thanks,

Adding to this top level item.  I'm seeing this issue all the time because we use a lot of child RadWindows in our solution.  This is a serious problem also because options like opening child as maximized is also being blocked.  I have replied inside the linked forum item mentioned in the primary above.

Hi guys,

There is a bug in the way IE accesses the document.activeElement property during the Sys.Application.Load event inside an iframe and more details about the case are available here: http://www.telerik.com/support/kb/aspnet-ajax/window/modal-radwindow-in-radwindow-in-ie9-and-ie10.aspx.

I can confirm that creating an event for the "OnClientBeforeShow" for the child RadWindow works.  It only executes a single line:

document.documentElement.focus();

The IE 10 error is gone now and the window opens correctly.  Thank-you,
