Two Problems
 

i) How can i make Screenshots?
ii) The Score Screen in Multiplayer mode after the match disappears almost immediately. How can I change that?

Screenshots are taken by pressing the Print Screen button on your keyboard..as for the score board idk.

i) press "Print" key -> y will find y screenshoots in ...my documents\my games\men of war\screenshoots\... or ...my documents\my games\outfront2 a2\screenshoots\...
ii) when games is finish & y are back in lobby from game (not multiplayerlobby) y can see score screen again when y press "results" on right upper corner.
