[Tutor] Quote and double quotes opens up File Explorer in Windows 10

[Ken G.]

Hi: In gradually moving over my Python programs (2.7.6) to Windows 10 
and using Geany 1.27 to modify or write up a program there, it is noted 
that whenever I typed in a quote (') or double quote ("), Windows 10 
File Explorer opens up. I end up closing it by typing ALT-F4 to resume 
typing as before. Is there a way to prevent the File Explorer from 
opening up whenever I use a quote or double quote? Is there another 
key(s) that does weird thing in Windows 10? Thanks.
