I just ran through the Windows OS validation download update deal. Upon restart, my mouse driver was gone, my pages no longer open full screen, the way I want them to, and no telling what else it overrode and messed with. I am afraid of what I'll find next. I don't recall doing anything special to get pages to open, big enough to see, when I installed the OS on the new drive, in December, does anyone know what I need to do now? It is only an extra click involved, but not the way I want to do things....
