This is why I finally gave up on the Magic Mouse.
I used my Logitech LS1 wired mouse for years, until the scroll wheel became notchy. I tried the magic mouse and liked it, especially the smooth scrolling. But, even after resorting to rechargeable batteries, the sudden disappearance of a document after accidentally side-swiping the mouse surface drove me to my current mouse.
I unchecked all the swiping preferences for the Apple mouse, but couldn't find a way around the side-swiping motion. I like my new mouse, but miss the smooth scrolling of the magic mouse.
