Our medical practice uses iPad Airs to allow patients to sign medical forms directly into our EMR via Safari. The problem we're finding is that many of them are having difficulty doing so because they will rest their hand on the glass while signing with the stylus. This results in the page panning around rather than them signing the form. Since a great many of them are elderly, they are having difficulty signing without resting their hand. Is there a way to disable the 2-touch panning effect in Safari? I've tried disabling multi-tasking gestures but it still has no effect.
