Google is locking me out

Weird. Google won't let me search. Says I'm sending automated queries. I'm not. Well, this is one way to get me to use Bing. Anyone else ever see this error? It's the first time I've seen this error. I assume that it will let me back on eventually. Ahh, the fun.

I wonder if running Google+ on screen has anything to do with this?

By the way, my wireless router is locked down with a good password. I wonder if my kids were doing anything on Google? Hmmm.
