I have since:
a) Swapped out sound cards
b) Rei-installed video card drivers
c) Tried it with no sound card installed
d) Tried it with the sound directory renamed
e) Tried it with new sounds installed
f) reinstalled Direct-X from Microsoft.com
Every time I use one of the latest aircraft that have been remodelled, SpitVIII, P-47N etc, I get a CTD when I click on the runway direction to fly.
Pretty werid. Pyro: is there a debug option for AH so I can track down what's causing this?
Up next: trying to play the game at 512x512 skins.
