odd interface changes I didn't ask for …

Firing up FM for another happy and productive day, and I see that the ? pods – interface components down the right-hand edge – have changed. I've explored the various options (Authoring, Review and so on) and none of these matches what I've been used to seeing; also, some of them (for example, XML/Structured) are empty.

What's more, Adobe Caslon Pro has mysteriously become unavailable!

Any hints or tips?
