I think ive found it (or the cause of one)
1st instance of ctd is while in god mode ...
If I am putting input on my joystick and i hit esc key to toggle the board up or down ... thats an instant ctd
2nd instance was while flying a 262 ,,, I had destroy objects up on the board and i hit the esc key while i had joystick input at the same time ,,was another ctd
now if i didnt put any joystick input in I could hit the esc key just fine to toggle the board up or down ...
Note; I was in the SEA on the new japan1 terrain at the time .
