Had to reinstall OS system. Upon reinstalling Access 2010, and my data, scroll wheel did not move the screen. Previously, worked in typical fashion. Now, have to use the scroll bar. Just plain old Datasheet view. Cannot seem to find any "setting" for this behavior, e.g., Navigation, or in any of the other options screens. Merely want the scroll wheel to work like it does in any other program, alternative to the bar. Recalled the same thing happened on installing Access to my lap top recently. Scroll wheel didn't work. Then, all of a sudden (i.e., I didn't think that I did anything, such as a setting, to change behavior) it started working as a typical scroll wheel. What am I missing? Thank you.
