Problem with year dropdown scrollbar in jQuery datepicker

The following will set year range from 1970 to current year and also take care of the scrolling problem.

.datepicker({yearRange: "1970:+nn"});

Try setting the yearRange option as well (which will set the range of years in the year drop down box). You can set it as yearRange: "-100:-21". Note that setting yearRange alone doesn't affect the actual dates the user is allowed to pick (you still need to set minDate and maxDate).
