I've been a frequent visitor to the Theatre of War 2 forum, but this is my first post, so I hope someone can help with my query. I downloaded the demo to play through bootcamp on a new iMac 2.93ghz with a Geforce GT130 graphics card. I've played part way through several times to assess whether it is worth buying the full game. Gameplay is fine, but I have one gripe - as the battle can take some time, whenever I have tried to save where I have got to the game crashes to desktop and there is no saved game when I relaunch. Is this a fault or can you not save the battle in the demo version? Hope someone can help.
