I can't test in 2.65 but this will work in 2.73.
Code:

scrolling: true, // Continuous slider movement if left mouse button held down
scrollInterval: 150,// Interval (in ms) between slider movement when button is held down
valuePrefix: '', // Prefix for callout
valueSuffix: '' // Suffix for callout
