If you are in circuit move & copy, you can try to use the set origin option from the RMB menu, before you start the actual move operation.
You can use the key in 'ms' (move selected) to do this. Select the items you want to move and type ms dx=-100,200 in the keyin command toolbar.
Thanks a lot for a very quick answer!
Do you know if there is any fix for the situation you select a group of elements and try to move them and they get out of the screen?
