Hope I'm not jumping in where I don't belong, but I just wanted to say that I've had the Perscan crash with intruders since I downloaded the D2D version in late December. I had hoped the 1.00.11 patch would correct the problem, but no luck. It looks like you gentlemen are hot on the trail, though... The problem isn't a "game-breaker" by any means, but it is annoying and detracts from an otherwise great game so I'll continue to follow this topic with high hopes and fingers crossed.
