It does not happen with your B24, the B26 or the new B26 multiskin, so I believe that it is a fault somewhere in the B17 files.
I just tried the default B17 skin and there was no problem either.
Symptoms:
If I fly a B17 and scroll to see the port engine and then back to see the starboard engine I get a lock-up and a CTD.
If I press F9 to get the external view and scroll to view in a full circle I get a lock-up and a CTD.
If I fly a 190 and intercept B17s approaching from head on I get a lock-up and a CTD.
I have tried several different exes, and versions of the transparency link files, but it made no difference.
Possible clues:
The scrolling problem disappears if I rename the planeS.3dz as pppplaneS.3d so that the planeS.3dz is not loaded.
However, the 190 intercept problem remains.
