This should be easy... brand new SL install and an existing gmail account. I have the email configured. Have calendar configured and syncing. But contacts... when I set up syncing in Address book, nothing syncs. When I exit Address Book and reenter, the option to sync with Google is no longer checked. I re-enable it and it does the same all over again. Any suggestions about how to get that option to stick? Update: OK so when I try the process with another account, it works like a charm. So what does that mean? How can I "fix" the gmail account in question to get it syncing?
