Acrobat always opens in second screen

Hi,
I have 2 screens. I don't know why, but Acrobat always opens in my second screen, even if I drop the window in the first screen. It doesn't memorize this action like all other programs.
The problem is that I don't always use the second screen, so I turn it off. And Acrobat opens in the second screen even if the screen is off...

Thank you
