Are you trying to move it or copy it? Different things...
You can select items in the schematic and then use the move command. Just hit M on the keyboard and then select the type of move. Make sure you're in the 'Editor' view, by clicking on the Editor tab at the bottom of the sch window.
Otherwise, if you want further help you're going to need to be a lot more detailed about what exactly you're trying to do, what exactly you do in the software, and what exactly happens.
