After I updated on Sunday to #21 and changed the Crosshair to "Damocles" I had CTD too if I use Arty-TD Mode with "G".
But I had no Messages on Screen, ony WOT freeze and back to Desktop.
Went back to #19 an changed back to "Jimbos" and it works, so I THINK ist might be because of "Damocles" in combination with 3rd Arty view?
EDIT:
Updated to #23 but used "Jimbos" instead "Damocles" and no CTD now.
