You can only do so when you have the 2.02 patch, to take snapshots of the Concourse (or final mission scores) you need to press < ctrl >+O
To take shots during flight, you press < ctrl >-< Print_Screen >
Now if you want to take shots during a replay, you need to use a program like Hyper-snap.
In all cases of using the XWA cature method there will be a file called frontscreen#.BMP or Flightscreen#.bmp that will be created in tyou XWA directory
