Nano Hog Front Panel Fault

I have a hog PC setup with a Nano Wing (and a Super Widget installed in it).

I've just upgraded the system to Windows 10, and Hog 4 PC to v3.12. Straight after I noticed that certain front panel key presses registered as multiple key presses, and using the hardware diagnostic I can see that each of the 8 keys on the right hand end of the panel 'light up' a slightly jagged horizontal row of 15 other switches. I assume that the front panel is scanned as a 16x8 matrix, and the symptoms look like a short somewhere in the matrix, ie a hardware issue. This hardware test runs separately to the Hog show software.

This is what the diagnostic shows after pressing 'right arrow' and 'all'



But I wanted to check this isn't a possible software issue, so can I ask if anyone else has had those symptoms? I have done the following-

I have mapped the wing and the super widget in the v3.12 software, and DO have dmx coming out of the widget.

I have also reloaded the nano firmware by powering up while pressing Next Page/Choose 1/ Choose 2, and had a confirmation flash after 15 secs or so.

This isn't the 'ghosting' issue of keys mapping wrong on a one-to-one basis, and for which there is a technical bulletin- the nano wing in question did have that fault and was fixed about 6 months ago.

Cheers,
Andrew
