I bought Command Ops 2 on day one. Have yet to play it because of this issue : (

Sorry for not being clear; my laptop has MS Sans Serif installed also. I was investigating my setup with your findings in mind Ranger, where the Microsoft Sans Serif fonts were missing.

Sad to report that the Microsoft Sans Serif font library is not the cause/fix for my dialog rendering woes. I finally got around to checking the font library on my Windows 7 laptop and noted that the Microsoft Sans Serif font is already installed : ( edit: correction...OS is Win 8.1

This sounds encouraging. Will share my results when I get the chance to try it out in a few days. My thanks to those who did some digging.

I would really like to play CO2 on my laptop but cannot due to the menu scaling issue. Holding off on expansions until this is addressed. Hope this receives some attention soon as I'm eager to grab KOAD.
