I know that they were trying to be helpful, but... By default, Windows 7 will run at the resolution that the screen has and make everything bigger in software by changing some settings, that makes things less blurry. The fonts on my laptop were bigger than the fonts when I connected to my test machine. I spent about 6 hours chasing google snipes until I figured it out finally. I'm on 3.4.0.160, BTW. Each of those number is a change that I made, some major, some minor.
