Thinkpad laptop, red "mouse" button/nub in keyboard does not work with version 4.0, Why?

IBM and/or Lenova laptop computers have the red button/nub in the center of the keyboard that acts with "mouse" functions such as scrolling up and down pages. After downloading Version 4.0 of Firefox this feature does not work anymore. Is it locked in some settings?

i figured it out! 1) go to control panel 2) click on mouse 3) click on the UltraNav tab at the top 4) for the TrackPoint, i have the Enable TrackPoint box checked and the "Use as pointing device with advanced features 5) click on Settings 6) click on settings again towards the bottom right 7) for "Scrolling Type" click on Smooth.

that should work!
