I attempted to install OperaXP on a thumb drive--portable. It installed over my Opera on my C: drive instead. Although errasing all of my tabs that I always have open, including Outlook, is not a big deal, now when I try to open my outlook, it goes to the sign in page, then it then directs me to a blank page. I did a repair insallation of Opera about 3 or 4 versions back--Uninstall, then option to repair. I can open Outlook in MicroEdge without a problem. I am out of ideas how to fix this problem.
