Hey Welcome to the forums.
3) the reason for this is the show was active when the show was last saved and/or the program was closed. Make sure you have all your lights and scenes on black out and scenes on INIT and then save and then close the program. I would really need to see the compu live screen by either a screen shot or email me the .ssh (show) file. My email is jamesk AT elationlighting DOT COM
5) Both are possible in compu live depending on the interface however usually 9 times out of 10 it is relative.
Any more questions or something you want explained further let me know by email or a post.
Sincerely,
