I downloaded & installed Nvidia GeForce G210 driver. Started CS6 . . . opened several JPG images . . . each was completely visible after loading. That sometimes happened before, so I'm not completely sure it's fixed . . . time will tell.
Now I have another (different problem) . . . The Type tool will not work. I get "Could not complete your request because something prevented the text engine from being initialized."
For what it's worth . . . each time I clicked to make the above Bold & italics I got a Windows Internet Explorer message "Are you sure you want to leave this page?"
EDIT . . . I rebooted (again) & everything seems to be working . . . EXCEPT the Windows Internet Explorer message "Are you sure you want to leave this page?"
