Boring Technical Question (MI: SE, Windows 7)
 

I was running MI: SE fine on my Samsung N145 with Windows 7 Ultimate, but yesterday I went to play it for a session and it opened in a window, not full screen. I then succeeded in getting it to work full screen, but completely screwed the aspect ratio in the process. Now whatever resolution I set it at, it's horizontally squished and won't run full screen. Has a Windows 7 update screwed me?
