I was messing with my personal settings in the control panel and somehow screwed up my display. Everything is "zoomed in" and all windows are "stretched out" (as in the 3 boxes in the top right corner are rectangles, not squares). I've fussed with my resolution and DPI. My resolution is at it's highest (although it made everything smaller, its still all stretched out) and my DPI is on the default setting. Is there a button to delete any modifications I've made? I have Vista...
