Hi there,That is a very interesting thing to hear about. I have never heard this issue before (though never searched for it), but did not think that this is the cause of my problems as well. A BUG. I work till 6 PM, get home by 7, and if I'm lucky and have some spare time, I get into the PMDG cockpit by 7:30 PM. Considering aircraft initialization, FMC programming, and so forth by the time my 737 rotates it's after 8:00 PM. Now you do not want to fly a trip more than 2 hours long at this time, because you have to go to work tomorrow. Imagine just before reaching T/D MS WXP tells me that FS9 has caused an error and needs to close, and if I were in the middle of something, my data may have been lost, sorry for the inconvenience. This is at 9:30, a full evening wasted, no time to restart, more like a pain in the butt. I have more than 1.500 USD worth of hardware and software installed, paid for every single screw and bit, and then what makes my evening a piece of crap is aBUG.Sorry for being this long, I felt I had to write it out.Bests to everyone. Cheers,Balint Nagy
