I am running a Dell Pentium 4 with XP OS. All of a sudden (last few days), whenever I go to an internet site, the page seems to be displayed in a slightly wider aspect requiring a slide bar at the bottom of the screen to slide left and right to view the entire screen. This has just started recently (I have two teenagers who like to fiddle with settings). I have tried adjusting through the display window in the control panel with no results. Does anyone have any idea what could have caused this sudden widening of internet screen sizes? (slide bar only appears when on an internet site). I have also tried changing text size to smaller and smallest settings--this also did not work. Thanks TJWeeks
