I am using jquery.momentum.js for an application on which i am working. I have noticed that the scroll bar used for displaying events is suddenly begin jerking up and down in small motions very quickly when i touch and move mouse pointer up side or down side.

I have tried to modify the configuration in js file but it seems it is not working , It is still begin jerking up and down in small motions very quickly when i touch and move mouse pointer up side or down side.

Here are the parameters i tried to change.

 fps: 60, // Frames per second in msecs. direction: null, // "vertical", "horizontal", or null for both. scrollDuration: 2000, // Duration of the scrolling animation in msecs. overshootDuration: 250, // Duration of the overshoot animation in msecs. snapbackDuration: 500, // Duration of the snapback animation in msecs. moveThreshold: 100, // Time between mousemoves must not exceed this threshold.
