Hello. My name is Lajos, I'm 23 year from the Netherlands.

I'm having a problem with maximizing windows, and I'm running 3 monitors using Surround (for gaming). Since my new Windows 10 installation I cannot maximize it to a separate display anymore by double-clicking the top of a window.

Unexpected behavior: when I double-click on top of a window, it maximize to dimensions I previously dragged with the corners of windows. Or it fills my whole surround resolution which is pretty annoying.
Expected behavior: When I drag a Window to another display, it should preserve the dimension so it will fit on that display (1680x1050) where the window is currently on.

Question: how can a window fill a display? Now I'm every time resizing a window manually and I need to focus myself to exactly meet the display dimensions, before it overlaps another dispay, lol. I can not stand it.

Regards, Lajos
