Absolutely infuriating problem. All of a sudden, anything I download to the desktop is INVISIBLE. I tried to have screen capture JPEG images go to desktop and they don't appear. If I open my desktop through users, I see the item there. If I try to drag that item to the desktop, it refuses because it says it is already there.... but it's not. I tried to download a PDF file to the desktop, same problem. Not there, but opening desktop through users finds it. Again, can't drag it, can't access it. I just have to delete it from the desktop opened through users. The only way to get anything to the desktop now is to download it into a folder, then open the folder and drag it to the desktop. Then it appears as it should. Major pain in the rear. I tried using my cursor to "lasso" blocks of screen looking for the invisible item, but it is simply not there even though the idiot computer keeps saying it is. This problem suddenly appeared for no reason. I have made no changes to the computer and have not downloaded anything.
