Cannot restore file from Time Machine

Seems like it's a bug to do with having a second monitor live! Turn that off, and then it works:

Parrot MKI9200 Poor connectivity with remote

This has continually been an issue, very slow to respond, then only working intermittently.

But it *seems* like the solution could have been quite simple all along! In the battery compartment, there is a small piece of metal that makes the connection with the battery. By pushing this slightly further into the centre of the device (i.e closer to the battery) the connection seems better and the unit is responding really well.

....... for now at least!
