Changing mouse behavior

[mdijb]

Using LR on a MAC with magic mouse.  When laterally swiping the mouse to scroll along the slide tray at the bottom of the window, The whole screen becomes locked and moves as a unit to the left and a screen showing some extras like a calculator and others, appears.  I have to click the rt lower corner to return to the LR screen.  This happens frequently and is annoying.

I think this is a Mouse behavior or OS behavior.

How can i turn this off?

Look in System Preferences for the Magic Mouse and adjust the settings to suit your needs.
