Screen image moves when moving the mouse

Question

I inadvertently changed either the mouse or expose settings last evening and now my screen is magnified so that some icons are off screen. If the mouse is moved the screen image jerks over to reveal the hidden areas in a horrible way. Does anyone have any idea how I can get things back to normal? AJ

You should be able to change the magic mouse's settings
and perhaps select to turn off some of the features which
have enabled the unwanted effects.
Since I have an older single-button Apple Pro black mouse
with the clear case and black/green circuit board inside, I
can understand the issues a newer design mouse brings.
Several multiple-button mouse products I've tried (not wi-fi)
were unsatisfactory due to the unwanted effects set into
motion by various accidental activations.
The Magic Mouse has a touch-surface, so you may have
to try and find out what settings have triggered the effects
you have no need for, & either change them, or turn them off.
The touch gestures sometimes activated by just trying to
use the sensor-laden top section of the Magic Mouse is
an area you may have to do some searches into; some
sites had discussed different matters regarding this item
and some topics include custom gestures. There may be
some kinds of custom software to modify the unit, too.
One site with a list of motions that produce more effects:
• "Add more gestures to your Magic Mouse"

{There probably are some other sites with helpful hints
about how to disable some of the existing ones. The
control settings in System Preferences may be a start.}
• MagicPrefs is a must download for Magic Mouse owners (freeware)

Other preference selection software to control gestures can be read
about in this linked web page with some comparison products:

Sorry to not be as much help as initially thought; and
hopefully some other answers will be forthcoming.
Good luck & happy computing!
