Files are not actively marked in Windows Explorer?

Have my notebook put on new. Since then something works in the Windows Explorer not as it used to, which is extremely annoying:

If I have several files in a folder (for example Pdf) and double-click one of them to open them, the folder window is no longer active in the background. This has the following annoying effect: If I close the open file and would like to use the arrow keys to select the next underlying file to open it, this will not work because the folder is not active (the file is highlighted in gray). I have to first (with the mouse) in the folder click, so that the file is marked blue again.

It used to be that - as soon as I closed the file - the open folder was again the "active" folder.

What do I have to change?

This is purely a matter of setting in the folder options.

It would be helpful to know which attitude this is

A clear, read and understand makes you smart!

I could solve the problem: Control Panel / Simplified operation / facilitated center for ease of use / using the mouse

There "activate a window by pointing with the mouse". And it works:-)
