Thinking about it, it seems to me that APT is waiting for some reponse from the camera after the start button is clicked, but the camera either isn't giving a response at all, or is giving a different response to what APT is expecting? Then pressing one of the buttons/turning the wheels forces some kind of refresh which gets things moving....
If it is any help to you I have some programming experience in VB.net. I am not sure what you have used to write APT?
I will send you a PM with my email address. I would like to help you get to the bottom of this issue.
Thanks
Adam
