I'm on Windows 7 Ultimate, I was Chrome browser I tried to open a tab, my current closes and a new one open, so I click on the tab(not the x) to see it and it closes I click on all my tabs to check, they close one by one. I try to reopen chrome from my task bar, mouse moves but nothing will click open. I can't even x out and close programs or folders I have open. I usually log off/on from keyboard or reboot and the problems goes away. but this happened several times this week. Anyway to fix this permanently other than Windows 10 upgrade?
