When I am away from my computer and the screensaver turns on (Webshots), when I return, my computer displays two messages : An error message ("GetDriveLayOut: CreateFile fail! Insufficient quota to complete requested service.") and a Webshots Desktop dialog box ("A locking violation occcurred while accessing Webshots wallpaper.bmp."). The only way I unlock my computer, then, is by rebooting. HELP!
