Safari 6 won't accept enter key

safari 6 worked fine for me until today: if I enter a term in the search/URL bar which is not an adress the enter key won't work. I press enter and nothing happens. It's different when I type a URL like "" then it will bring me to that page after hitting enter. but if I type for instance "apple mac" nothing happens after hitting enter. I already did a safe restart but the problem persists...
It's the same for me, and it's driving me insane.
There seems to be no place to download safari and no easy way to reinstall it. When clicking on the magnifier glass in the search bar I can click on "search history" or "search page" but clicking on "google search" won't work.
