screen shrinks when mouse moved downwards from top of page

Sounds like issue with the mouse scroll wheel.

Expand Mice and other pointing devices.
Right click on the Mouse and click uninstall

Press Alt + F4
Press the Windows key + X
Press the letter U
Press the letter R

Andre,

So far that seems to have helped a lot!!!

It does shrink the screen nearly as much. Before I uninstall the mouse driver the screen would shrink when ever I moved the cursor downward, regardless where the cursor was.   Very frustrating.    

Not it only does that when I double click at the the top of the page.  Still unwanted but not nearly as frustrating.

Thank you !

Now if I could only fix the cursor from jumping back to where the  cursor "Pipe" stays put!   

I know this is O.T. but I really wonder how to make the cursor pipe follow the blinking cursor that follows when and where you are typing. Not sure if that make sense. 

But again, thank you!!!!
