I think I might have 2 fixs if anyone is encountering any problems with speedy over scrolling of the hotbar with your mouse wheel!
1st Simply start your world any unplug your mouse dongle or cord whole in the world and plug it back in. This fixed my problem with "flash gordon" overscolling with my mouse wheel. Keep in mind I'm using a ASUS Transformer Tablet Model No: TF100
If that doesn't work try exiting the logitech mouse and keyboard settings task in the task bar.
