Been playing Arma 2 since it's release. Have BAF, CO, PMC, and forget what else. I've never had the Black Screen problem until the 1.59 patch. My specs:
Windows Vista Home Premium Service Pack 2
Intel Core2 Quad Q6600 2.40GHz
3 GB RAM
NVIDIA GeForce GTX 260
Again, have never had the black screen problem until I downloaded and installed the 1.59 patch a few days ago. Don't know if it's related, but seems fishy.
