In some situations, you might find that when you right-click the Recycle Bin, you can neither empty the Recycle Bin nor access the icon's Properties. Also, without your direction to do so, the files are bypassing the Recycle Bin and being permanently deleted. This problem may arise when you have a fixed hard disk that is marked as a removable drive.
I see a plus sign to the left of a drive icon, but when I click the icon, the plus sign disappears.
