iTunes-type alternate colored lines in scrolling list field (Jan Schenkel)

[Greg Saylor]

Hi Jan,

Sorry for a second email on the same subject -- hopefully this won't
cause confusion for you.. I did what you said below and it works except
that the pattern does not seem to scroll when the field scrolls...  Am I
doing something wrong or did I miss something important?..

>  end scrollbarDrag
