I have had my Nexus 7 for a couple of days. Today it started getting whacky. If I do a voice search.."What is the temperature?" The card will come up for a brief second (1/5 of a second) and go back to main screen.

In fact if I ask any question. Such as "Map of Chicago." The map comes up for a brief second and  back to main screen it goes.

It worked fine yesterday. Am I missing something?
