For zing, check you have new-style bookmarking set in prefs, that you don't have a sneaky uppercase letter in your login email, and that you're using red-icon zing.
I have seen a few bookmarking errors on the server, will take a look.

Seems to be working in Zing now without me doing anything. How odd.
