Hi Stew,
the only thing, that worked for me, was to UNtick the corresponding option in the fixer software under EFFECTS. But be careful: Converting all shockwave lights will result in other problems, e.g. strobe lights on AI aircrafts are only visible over very short distances.
Steve had a brilliant idea: First of all you have to copy ALL shockwave effect files to a save folder. Then convert all shockwave lights via unticking the option in the DX10 Fixer. After that, copy all saved shockwave effects back to your Simulator effect folder, exept the landing light effects. So, you can enjoy landing light from nearly all perspectives without loosing the visibility of others.
I hope you can follow my instruction, i am not a native english Speaker
