This is odd... I have a 1440x900 resolution monitor. At first I had trouble getting it to change resolutions - it would say it was at 1440x900, but it was really a stretched, hideous-looking 1024x768. I had to manually change the resulution in the user.setting file to get it to really work.
But now the text (in the menus, for instance) is blurry when it's in full screen mode. The words almost run together. When I switch it to windowed mode the text is sharp - not blurry or running together at all.
Anybody have any idea why this would be the case?
