I coded the “game” just like in the tutorial.
In the Editor and in Windowed Mode everthing works just fine.
But when i Build & run in Fullscreens mode, my Buttons seems to be disabled.
No hover or click effect, nor does he perform any OnClick()-event.
When i configure the Screen-resolution just to my Resolution conifgured in Windows everything works fine. Even in Fullscreen-mode.
