I used my dell desktop earlier today without issue and without adding any thing. I tried it again tonight and the left click on my Logitech wireless mouse no longer works. My first thought is that the scroll lock key was pushed, but I don't have one on my wireless keyboard. I tried pulling up the onscreen keyboard but I'm not able to choose scroll lock because the left mouse isn't clicking. I tried going into command prompt admin and running the scan that took forever with no problems found. I don't have a wired mouse but I will get one tomorrow to see if the mouse is the issue, but from other threads it seems to be a common theme with Windows 10. I tried to operate mouse functions with my keyboard but that didn't work either. What can I do to fix this annoying problem?
