Mediabase scroll bar issue

I'm running Producer & DVS 7.1. Both have an issue when scrolling through the Mediabase:
If the scroll bar button is at the top of its range on screen, it's not at the top of the range of the actual media base. When I click on it I often get punted to another place in the mediabase and loose track of where I am. Possibly not a big issue but it does cause frustration when browsing for tracks. Also the scroll button itself is too large and the same colour as the background - can this be changed?
Hope you can help,
Cheers!
