Windows 7 Professional. When I shut down 8 Feb things were normal. When I powered up 9 Feb I immediately saw differences on the screen. The taskbar's minimized windows are still there but the print doesn't have enough contrast. If I touched the box for an open file before, all other files were stacked above it for me to choose one. Now I get mini windows that I can't read. The top line in word processing files changed from dark blue to something faint. That bar used to show [filename] and WordPad; now it looks like someone smeared Wite-Out on it, so I don't know which of several open documents I'm looking at. (There's more.) My question is: Am I unlucky or did this happen to anyone else? My last update was 11 Jan 17, and I swear I didn't mess with the control panel.
