There is no way, that I can think of, to select objects in the background. However, if you move DEV16 to the left so the wire ends appear on the pins (1-2, 2-2 and 3-2) then they will be automatically connected. Or you can RMB on the wire and choose "Move End" then it appears on the cursor in stretch mode ready for reconnecting on any pin.
I hope that helps,
Thank you for your reply, the moving of DEV16 to the left and letting the pins get automatically connected really helped.
(I coundn't however get the 'move end' option on the 'drop down menu' by selected the wire and then RMB - I think this is because the wires at 1-2, 2-2 and 3-2 needed to be connected before they could be moved.)
The design browser on the left can sometimes make it easier to select a specific object (or indeed finding anything in your design)
You can right click on a pin for example and select Zoom Selected to take you there (it also selects the object for you).
This may help you.
