We have upgraded to SF 4.0 RC 2 and now, 2 custom control widgets that we made, lock-up the edit-a-page screen. We can drag them to a drag-widgets-here box, and publish the page, but when we open the page, in the edit-a-page screen for editing, that screen (the edit-a-page screen) pretty much has none of the functionality that it should have: the Publish button does not appear, the buttons across the top which are visible do nothing, and you cannot drag any of the widgets - neither SF ones, nor our custom ones. AND Firebug shows us that the page gets an error: "$telerik is not defined."
We used the js from the tutorial here
So to reproduce the error you should be able to try to put a custom control widget, that you created based on that tutorial, is a SF 4.0 RC 2 version of Sitefinity.
