Error rendering control - strange message

[Clive Hoggar]

Hi

I am seeing a very strange message at design time on a previously good master page, and
it may be something to do with a potted application that I have been using to debug elsewhere..

 Error Rendering Control - RadScriptManager1An unhandled exception has occurred.
[A]Telerik.Web.UI.RadScriptManager cannot be cast to [B]Telerik.Web.UI.RadScriptManager.
Type A originates from 'Telerik.Web.UI, Version=2009.2.701.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4' in the context 'LoadNeither' at location 'C:\Users\Clive\AppData\Local\Microsoft\VWDExpress\9.0\ProjectAssemblies\pb6zak8y01\telerik.web.ui.dll'.

Hi

Thanks Shinu 

I found the answer in the second thread. I had reloaded the dll into the bin and just needed to close 

VWD and reopen it avoid having the duplicate version

Thanks
