Thanks, another question about the 757, is it usual for the system to shut down after 15-20 minutes after takeoff. The screen will freeze, and you have to minimize it, and on the screen is a message concluding that the computer has run out of avialable memory, and then FSX shuts down. I understand that the 757 base package is not for vista, and may encounter problems, I took the chance, and am wondering if their is a way to avoid this. It is hard to find an IFR flight under 15 minutes. If not, thanks anyway. Spenser Critterton
