    I'm getting the following js errors when trying to use RadListBox as in the 'first look' demo (transfer items between two listboxes)

    Line: 2
    Char: 13
    Error: '$telerik' is undefined
    Code: 0
    URL: http://localhost:1653/Lighthouse/Candidate/listbox.aspx

    I get three of the above errors followed by ...

    Line: 111
    Char: 1
    Error: 'Telerik.Web.UI.RadListBox' is null or not an object
    Code: 0
    URL: http://localhost:1653/Lighthouse/Candidate/listbox.aspx

    Has anyone seen this?  Did I miss a resource file somewhere?
    Our company just moved from the Q1 release to the Q2 release.

    Thank you.
