Hello,are there any recommendations on installing both models in the same FSX installation?The reason why I'm asking is that in my current FSX installation 744 was first and then 737NGX.After months of storing 744 in the virtual Hangar i have some strange behaviourof the 744 like permanently switching of automatic speed controll duringVNAV operations and in inbetween some minutes the thrust goes to idleand comes back after some seconds.So i suppose maybe some interactions. Before i go reinstalling the 744 i want to ask.Thank you in advance.Andreas Hövel

No problems here. You may just continue with the reinstall.
