Hi, When you drag anything it is moved from one folder to another. If you hold down the Control key while dragging a copy is made in the new location and the original is left where it was. Try dragging it back with Control down. You could also make a new shortcut in the old position. Right click the working Icon and click Properties. That's the info needed for a new Icon. Or browse for the info.
Good luck, Jim
