Small screen problem

[dgg9879]

Yesterday the game took up the whole screen but today it was smaller than the whole screen. I tried re-booting a couple of times but it was always like this. It was still playable and enjoyable but can someone please tell me how to make the screen bigger. Even clicking on the windows "make bigger" icon in top right didn't solve the problem, the game window became full size but the game itself was still in a small window
