Bsplayer open square window on new movies
 

Every time a New movie i play with bsplayer, it will create a Square window.
I usually press the key 'A' to circle between aspect ratios. But it is bugging me for some time. I bet is not a bug, but a settings somewhere that i completely overlook (even if i look into its settings a lot).
It will memorize the aspect ratio and other settings if i will re-open the same video file. But for completely new movie-files, its square every time.
Current version bsplayer pro 2.70
Please help, and thank you!

In options -> preferences -> video, in bottom center you have a drop-down box named - when opening change to. Check if "no change is selected". And also check the full screen setting below.
