I can check my settings without fully opening ccc. In openGL settings, it shows triple buffering. It doesn't show what the settings are. I was in and out if it so many times, I had to have set it for ' on ' at some point before the install. I've never been in the habit of writting down the changes I make for anything. I tell myself I'll remember. And as always....
Anyway, it was acting on your advice I decided to give it another shot. Thanks.
