It seems to be an offline thing. I can fly for hours online with no problems, but I have had lockups offline.
BTW, this release has been one of the BEST IMHO. Tons of new planes and fantastic weather effects that truly lead the industry.
If you have a bug with offline play, you should post details in the Bugs forum.
