I have a customer using Windows Vista on a Toshiba laptop. All of a sudden their icons are misbehaving. If there is a row of icons clicking on any icon in the row causes the icon at the very right to run its shortcut. This also happens in other windows like Control Panel for example. I suspect a virus but they have kept their virus software up to date and run regular scans. Does this sound like a virus or is it a problem with graphics drivers?? Any help would be appreciated.
