JScrollPane

Bringing the jQuery jScrollPane module to Drupal.

This gives you the ability to let JavaScript create the scrollbars of a div of whatever element you need which actually gives you more control over stuff like styles, callbacks, etc.

Maintenance

I (opdavies) am currently maintaining the Drupal 7 version of the module and will soon be backporting the majority of the changes back into Drupal 6 as a 6.x-2.x version. I'm personally not supporting the Drupal 5 version although one of the other maintainers may be willing to do so.
