$CellContext` Problems; how to solve them?

Seeking wisdom and knowledge how to understand and solve $CellContext` problems in reported errors. Spending time thrashing about trying to figure it out is not helpful. The Doc Center is rather unhelpful. Thanks.

ps. why does dynamic prevent scrolling of a Pane? I have ran into this several times in different UI development. Is there a proper way to use Pane in a complex Dynamic?? I am filling it with a list of ActionMenu objects, which work but can’t scroll the Pane to see them all. Thanks

Do you have an example of the type of problem you are trying to solve?
