Whenever I am in my Lancair Legacy and then I want to swithc airplanes. I choose the Manufacterer and model then I press Okay, I wait about 20 seconds then it just goes down to my desktop. ❓ There must be something wrong with the plane, right? It works only when I start in the Legacy, then I want to switch.
If it works with other aircraft and just the legacy crashes, yes then there is a problem with the legacy.
Look for another designed by someone else.
Is this the one you have.
That is the Legacy I have. 😕
That's the only one I can find, it won an award. Try unloading it and reinstalling it.
