Windows 10 and Gmail cut-and-paste problem

Report
-
I recently acquired a new Windows 10 computer. I have set it up with Gmail. I cannot cut and paste from a Gmail I received to another Gmail. However, I can cut any portion of a received Gmail and paste it into Word or other types of programs. I am able to do this on another Windows 10 computer and it works as it should.

What can I try to make this work?
