In my case Windows did an automatic update and now I have three problems: 1) the mouse click isn't always recognized; 2) the pop-up or drop-down menus are blank and sometimes very tiny or narrow (not sure they're actually blank, but the menu items can't be seen); and 3) text for some functions has become very tiny. I've tried restarting multiple times with no change. I can't do anything to try to fix it because my menus aren't visible and so I can't get into Control Panel or Settings, when I try to type in the search box to get to either place no text appears.
