no, that was not exactly my question ;-) It is no dome opening code I was referring to.
But it may happen that only part of the startup script is executed e.g. the CCD camera is powered up and cooled down when an unsafe event stops the script before this is fully completed. ACP gets lost in this condition and the camera keeps on running doing nothing until manual user intervention next morning. No shutdown script initializes.

Keep on traveling and visiting your CA customers, I can wait until you return home or you are going to visit your European customers :-))
