Hi Dean. Thanks for the kind words. Yes, it did take a very long time to develop CFS2 Korea & sort out all the bugs. It's been my ambition since CFS2 was first released. You won't get the full effects until you fix that problem. I've never come across it before. I don't think installing addons would cause it. I've installed all sorts of stuff including the Axis/Allied expansion packs without a hitch. I still think a duplicate install of CFS2 is the best way over it. It would at least confirm if the problem is with the sim, an addon or even your keyboard. I always test a new campaign on a fresh duplicate install of CFS2 before posting it.
Set the realism to easy by all means. Then you wouldn't have to worry about those "exploding jets". Those jets are difficult enough to fly in combat without using Full realism.
I've never tried IL2 although I've heard good reports on it. CFS3 won't run properly on my old rig but I saw enough to realise it's not for me. I much prefer CFS2. I think we've proved there's a lot of life in it yet. CFS1 is also still going strong & runs like a rocket on the latest systems.

Hope you get things sorted out. If not, please mail me direct & we'll do our best to figure it out.

PS. Silly me. I've just figured out the cause of your problem. The wingmen won't attack a target unless you padlock it. This might be connected with your Tactical Display problem. Fix that & it should be OK.
