In our application we are using an asp:ScriptManager in the master page. The master page has update panels and Obout contorls in them.
We have another page which uses this master page and we have Telerik controls in them. Application users are getting the following error message when accessing the application from a different WAN.

Message: Sys.InvalidOperationException: Type Telerik.Web.UI.Orientation has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.

I tried replacing the ScirptManager to RadScriptManager in the master page but Obout controls are throwing errors.
In an earlier scenario in another application which uses only update panels and telerik controls we saw the same error messages as shown above. We then replaced the ScriptManager of these pages with RadScriptManager, this fixed the problem and we did not receive the error message anymore.
Now in this scenario I am not able to replace the script Manager with the RadScriptManager. Please let me know if you have any way out.
PS: This error is being thrown when we use telerik controls and asp:ScriptManager and when the application is being accessed from a different WAN at a farway distance from the server location. we never see this error when accessing the application from VPN nor when accessing the application from the same LAN in which the server are.
Thanks in advance.
