When you change the game's resolution, the menu's shouldn't be cut off just because you made the window shorter.
The menus should resize to fit the current window size.

While you're changing the size of the window, menu is not changing it's size also you can not change it back if you minimize too much the window's size.

Yeah, that's why I want it to be resizable.

You also can download version 4.2 (the latest one) and play on it because size isn't the same in all versions.
