I am still using XP and downloaded all updates left today, to be fully secure. Other computer also updated. downloaded pdf in X and saved to desktop but then box disappeared so I could no longer open pdf while in browser. Had to go to desktop. Uninstalled x and wetn back to 8. Made no difference.
Can anyone explain why this has happened? Is XP on this computer being difficult? Don't run other pdf software. Found X rather unstable. Crashed if I was printing. Geek told me it's an XP improvement to protect me but other computer still has that lovely box.
