Secret mouse gesture zooms page?
Every so often I inadvertantly zoom a browser page by some apparant combination of moving my mouse and moving my finger on my mouse but I can't quite figure out what I am doing that makes that happen (but I wish I could stop it from happening...it's annoying for it to happen when I am not specifically double-tapping to zoom). Does anyone have any idea what it is I might be doing that is causing this?
iMac, Mac OS X (10.7.2)
