I have a Dell Dimension L667r that my sister uses for instant messaging and such, and we just redid windows yesterday. everything is fine except for the screen size or whatever. everything is too big, but it wasnt before we redid windows. i right clicked the desktop, went to properties, hit the settings tab, and the settings are at 640x480 right now with 16 colors. and the bar wont slide to make everthing smaller. please help with this. (the computer really sux, its like from 98 or something and has a 6 gig hard drive, so nothing too high tech plz) lol
