XP home. A couple of problems. When I click on the directory "Local "c", nothing happens. I can right click "open" and the folders will open for viewing. The folders will open OK. When I click on an executable nothing again! Also, CD Roms are the same thing. No auto-play. I can right click and see what's there, but I can't run anything. It worked OK to reinstall Windows (repair install), but it won't work right IN Windows. I've tried 2 different CD/DVD's, a plain CD player, and a USB CD Rom, and they are all the same. I even tried a new profile - no change. The computer was having many problems, so I just rebuilt it (new mobo and memory). That's why the repair install. It had this problem before AND after the new install. I don't know what the kids did to this one!!! The icons open OK from the desktop.
