I have a Tartarus v2 to replace a Nostromo. I have done this before but, gave up because the Synapse 3 software was proving unreliable and so returned to the Nostomo and sold on the Tartarus. Now on Synapse 3.5 I decided to give it another try, initially by keeping both the Tartarus and Nostromo connected, just in case there were issues again with the Synapse software. It is just as well I did because yesterday all was working fine but today, with the Tartarus, only keys programmed to keyboard shortcuts work, those for URLs and loading programs (from the PC) do not. The keymap selection, together with the coloured indicators work fine.

If I am unable to resolve the Tartartus isues then again I will need to keep with the Nostromo (on Synapse 2) and also again, sell on another Tartarus v2.
