I created a custom scrollbar in catalyst and relayed it to the guy who works in builder in my office. He is telling me that when he applies it to whatever he is coding that the unusual height of the thumb changes the color of the track behind it for about a half inch in each direction. My thumb is about 20x20 pixels. He tells me that because it is not a standard height of a normal scrollbar that it is auto correcting by changing the color of the track. I know this has got to be wrong because there are many different heights to a scroll bar. can anybody help me out so I can prove to this guy that it can be done.
