On my old XPsp3 machine, I could go to a folder, select several files attached to several programs, then right click on this group of several selected files and click "Open", whereupon each file and its program opened. On my new XP machine, when I try to do that, select the files, right click and click "Open," nothing happens. When I select just one file and do the same, it works. Therefore, I've lost the ability to open multiple files, using the most currently available XP. Why?
