Magic Mouse doing "swipe back" when trying to scroll down post-Yosemite
I've been using my magic mouse for 3 years since I purchased my iMac, and have never had any issues with it. Since upgrading to Yosemite, much of the time (enough to be extremely annoying - 20% or so?), when scrolling down on a web page, the mouse reads the gesture as a swipe back instead of a scroll. I've attempted to hold the mouse at a different angle, which is uncomfortable and doesn't really help any in any case. Is there a way to recalibrate the gestures so that it re-learns what scrolling down looks like (and stops going to the previous page, gah!)? Another solution?
iMac, OS X Yosemite (10.10)
