As the title says. Whenever I use the Fn keys to change the camera angle or Alt+O to use "End Mission" to exit a mission, the entire PC crashes. This is on Windows 98.

On the bad, new Windows 11, the same behaviour, exactly is the current issue, except it doesn't crash the entire PC but the game. The crash module is pointed at "flight.dle" file.

Has there been an official patch for it? Or any unofficial modder who got the Longbow Glide version to work fine.

I applied the Glide patch on the CD 1.03F game, and not over the 1.04F patch for the DDraw version.
