Here's the 1:30 video of the problem

Say I have a desktop 1 with MS Word open. If I then open another desktop (desktop 2), and then open a word file from my hard drive on desktop 2, windows 10 will take me out of desktop 2, put be back on desktop 1, and then open the file I requested. I then have to open the desktop switcher, and manually drag the word document from desktop 1 to desktop 2.

This problem occurs with all applications (chrome, file explorer, the settings application etc.)

Also If you are reading this, could you tell me whether you are experiencing the same problem?

Thanks in advanced for the help!

(this is on Win 10 pro 64 bit)
