autofill is no longer working
Since the more recent updates, Autofill is no longer working in Safari 6.1. The Autofill alert pops open as I'm filling in an online form, but when I click on it, nothing happens. I've tried the suggestions to change Safari preferences, but I've already selected "Using info from my Contacts card" and double-checked that my Contacts card is correctly filled in. Safari and Contacts don't seem to be communicating at all. Any other suggestions?
