Whenever i am editing and i go to the webbrowser for half and hour and i come back to the program, the window arrangement is totally wrong. I have my own personal window arrangement that i arrange myself, so if i just reset the arrangement i have to arrange it all over again. Why does it always do this?

I use Magix Movie Edit Pro 2016 plus, i have windows 10, 64-bit,
i have this: Intel(R) Core(TM) i5-4210U CPU @ 1.70GHz and 8115 MB memory.
