I see that the scripts are loaded from the AjaxControlToolkit assembly (it is present in the path to the combined scripts). This is not a known issue with RadWindow, so at this point I can suggest the following:
- try replacing the RadScriptManager with the asp ScriptManager or the toolkit's script manager to see if this makes a difference
- since it will, most likely, have no effect, try removing the AjaxControlToolkit assembly from the project (even deleting the file) because it is known to change some of the MS AJAX scripts which can break something that relies on them, like our controls
Other things you can try are:
- using the latest AjaxControlToolkit assembly to see if this helps
- attempting to force the correct AJAX scripts by following this thread
or simply referencing the MS AJAX scripts from their CDN through URLs.
