[opensuse] Minimum, Maximum buttons missing

I have lost the Minimum, Maximum buttons on all web pages and in the openSuse pages as well. I have gnome desktop, and openSuse 12.1. Only button on any page is the close button at the top right. The Min and Max buttons that were next to the close button are gone. Can I get those back?
