Just a thought,
It sounds like you have your graphics driver configured such that it defaults the 2nd screen to a resolution or scan rate different to that of your projector but, when you plug the projector in it forces the resolution or scan rate to change.
If you go into display settings and check out the settings for your 2nd display when the projector is connected, then disconnect it and check the settings again and change them to reflect the settings when the projector IS connected. See if that helps.
To err is human, to really foul things up requires a computer!
