How to change the color of the scroll bar in a scrolling panel?

Speaking of Updates.  TOO Many - TOO Often - TOO poorly thought out and full of bugs. 

I have clients (corporate) that cannot absorb this many updates and so they fall many months  behind because their IT depts. won't test and update apps that frequently.  

The number of claw backs has also left them confused about which version to even test - we've already had one where a serious bug (corrected in the following release) was distributed across the training organization.

Just my editorial thoughts.
