When I right-click on File Explorer, it shows a list of the files in my quick access. When I choose a file and left-click on it, it no longer opens the file. I have to right-click on the chosen file and choose the 'open' option from the drop-down menu and left-click. This works but I would like to revert to the default setting of opening the file when I left-click on the chosen file. Thank you.
