Windows 10: Double-clicking opens folders but not files

When I double-click on a folder, the folder opens. Good.

But when I double-click on a file or document for the first time, it doesn't open (i.e., it doesn't launch the application to read that file). Instead, the filename is shaded and there's a box around the filename as if I had selected the file and then tried to rename the filename. I have to deselect the filename and double-click on it again to open the file.

I figured the mouse clicks were either too fast or too slow, so I tried adjusting double-click speed in the Mouse settings in the Control Panel. But no setting, either fast or slow, fixes the problem.

Any ideas?

I'm running Windows 10 version 1909. I have a Logitech MK345 keyboard/mouse combo.

Single click or Double click - more productive ?

I use default settings. Double-click is used in Windows Explorer to open folders and files but I open files and folders with hitting Enter button. It's my old habit from MS-DOS and Norton Commander days which I ain't gonna change.


IIRC doors in Doom I and II are opening via double-click lol

 

Single-click or double-click?

As the title says, do you single-click or double-click on your shortcuts to open your apps?

I'm a fan of single-click, the only downside is that often when I click on a message in de list of my mails in Outlook it can open the mail in a window...
Not always but besides that, single-click works best for me.

 

Single-click or double-click?

Yes.
