I have a panasonic MiniDV palcorder, it used a USB to transfer pictures from the camera to the computer. Usually when I plug it in, a little thing in my tool tray pops up. When I go to unplug the camera from the computer, I have to click that to "safely remove device" and then Ican unplug the camera. I went to do that today, and the little thing never popped into my tool tray. BUT I went onto my sisters desktop, and it sshows the camera plugged in, like it should. Why wouldn't my desktop show it too? It's bizarre. I had to use my sisters desktop to unplug iit safely. If I don't do it this way, and just unplug it, my memory card messes up and erases all the pictures. HELP!
