Ok I have worked out what the issue is, when i was selecting track one, for some reason, maybe a bug, it did not select all of the audio track, and so when I was moving the track back, I was putting it on top of the unselected audio and that's the reason it was snapping back.
When I moved it a huge amount it worked but then putting it back didn't because the unselected audio was still in its original place, just a massive bloody headache at four in the morning. I am going to start again and try selecting the track but on the audio line instead of the video, hopefully that way it will select the whole track and nothing else.
Thank you both for your help I will let you know what happens...
One more thing, I now have an unlicensed copy of videopad on my computer, once this is done how do I get back to where I was?
