Forgive me ignornce on this, what am I turning? And this is when Play is pressed?
In the first part of the video I can press Play and you can see the small cog slightly turning. If I press stop and the try and press play again, the button just won't press in and I think as you say at this point it doesn't latch
At 51secs in the video I again can press play but as soon as I press a key on the computer, the play button depresses
