Hope I'm doing it right. lol! Went back to my original post, clicked "answer" and posted the link. Much appreciated your help on this. The sim doesn't crash all the time, but I've had random ones when for example reloading a few different aircraft. One crash was clicking on the "arrival" approaches in the default 747 FMC. etc. their just random and not one thing causes it. Thanks, if I have another crash I'll post that link too.
