Problem resolved! (Sort of)

That is, I am again able to play Quick Combat, the KW F-86 against the Mig-15, without a CTD every time I score a guns kill on a Mig.  The downside is I still haven't tracked down the source of the problem.  Let me explain.

I have an external Drive (G:) for backup and storage.  I had a backup of CFS2 from sometime ago before my problems started so I restored CFS2 to the G Drive and ran it from there.  Presto, I was even able to use the CA-27 Australian F-86 version without CTD on guns kill.

So I'm now in the process of comparing the 2 installs to try to track down what is causing the CTD on the C Drive install.  The first thing I noticed was the F-86 model on the G Drive installation was not the latest but an earlier version, so I tried it on the C Drive install but it made no difference.  I'm still working on it and it may take a long time but at least I can now shoot down a few Migs when I get the urge.

Thanks to all those who tried to help, especially Hagar and Dirt Man!
