Anyone on Mountain Lion yet?

I haven't upgraded yet because I'm waiting on a response from the Up-To-Date program. I assume that, newly-downloaded, Antares won't run due to Gatekeeper restrictions. I'll probably release a new version just to cover that problem.

For anyone who has Mountain Lion, are there other problems you notice? I guess I don't know what would happen other than a crash, but I'd certainly be interested in that.
