Hi,
i'm using Visual Studio 2008 with SP1 and Telerik Controls fro WinForms Q3 2008 SP2 and i have problems with the Element Hierarchy editor on a form: on every RADControl i chose to 'Edit UI elements' the Editor window appears, but when i move from root node to another node the window disappear and Visual Studio starts to show the message in object (RootRadElement cannot be converted to type 'System.Windows.Forms.Control') and i must restart the IDE. Any suggestion to resolve this problem? i cannot work in this manner....
