The horizontal scrolling thing is especially infuriating. If I just happen to touch the mouse with a finger and then move the mouse to the left or right, my active document scrolls out of view. Whoosh! Now you see it, now you don’t! For example, if I’m writing in Word, all my text suddenly vanishes beyond the edge of the Word window leaving me with a seemingly blank document. Grrrrr….

Why would anyone ever want that to happen? What is the point of it? Is there any application that anyone has ever used in which this is a desirable feature?

I tried using the Mac’s built-in mouse configuration tools but they didn’t fix the problem. So I did myself some Googling and pretty soon I discovered that I’m not the only person who finds this behaviour frustrating beyond endurance. People have tried to solve it all kinds of different ways. Some have run configuration scripts in the Terminal (but these, alas, only work for the Snow Leopard OS and not for Lion which I’m using), some have taped sticking-plasters over touch-sensitive areas of the mouse. Others have just thrown in the towel and bought a non-Mac mouse.

Eventually I discovered that a much nicer solution exits and I recommend it to anyone who has fallen out of love with their Magic Mouse. It’s a free configuration tool called MagicPrefs and you can get it from http://magicprefs.com. It installs itself into the System Preferences folder. And it is just great!

I’ve used to disable all horizontal scrolling and to permit vertical scrolling only when two fingers are used (so that a random finger-touch won’t send my documents whizzing off the top of the screen). These two changes have relieved at least 90% of my Mac irritations. The program also lets you make other changes to the way that clicks and taps and swipes and drags work. If you have fallen out of love with your Mac mouse, MagicPrefs may help to heal the rift…
