....apparently my children have hit a key board chord of which i am unaware... when I attempt to scroll or advance the scroll one screen at a time...the scroll bar drops to the bottom and immediately scrolls in reverse to the top this also occurs within an app with the mouse...any advice how to revert to normal settings??? my feeble attempts to search sys prefs have not found a solution Gary ----------------------------------------------------------- For information about MUGLO: http://www.freewebs.com/muglo -----------------------------------------------------------
