It would be interesting to know if Marque has just changed his display, because if not (and if it all looked okay beforehand on the same monitor) I stil think that the image aspect ratio must have changed. According to my quick calcs the screenshot is 1360 x 768 - which is a perfectly respectable monitor size, but well off the 4:3 ratio, so yes, it could be the display size causing this.

Have to say though that my monitor is not 4:3 (it's 1280 x 1024, which is 5:4) and I don't get those strips with an image of 4:3 aspect ratio.
