Thanks, that was the final piece [and I had to clean out all old installs, registry items etc and start from scratch- but it was worth it). I now have free flight Blackhawk and your very detailed and brilliant cockpit. See before and after shots below. Close-up graphics are excellent, pull-back pixelates/shimmers a little, and for some reason your cohokum.exe doesn't recognize the Cuba terrain and crashes the game - the other maps I tested (I went from Afognak up to Jordan - will cycle through the others) run fine. Now that I am here what else should I check for? .
