Quite often when I am browsing via Safari (or Google for that matter), touching, beginning a scroll gesture, or resting my fingers on my mouse results in an unwanted zoom in action. I can usually correct the zoom problem by double tapping the mouse to get back to normal view, but not always. Sometimes I have to close the browser window and start over. Has anyone else experienced this? I've been thinking of getting a trackpad to replace or supplement my mouse especially when browsing. Would I get better and more consistent gesture results using a trackpad?
