Problem when resuming saved flights

[killerbunny]

have you tried hitting PAUSE just before saving or shutting down? Sounds like it might solve this ...

Thats what I do and it works fine.
When I reload the flight I have time to check all the values and gauges.  I never had any problems with the AP

I'm doing further Google researches on this, and it seems that the problem is very aircraft (or panel) specific. Some addon planes (or panels) save all data, some don't. Even some payware products admittedly lack this function (the PMDG 737 NG, for instance). No wonder not everyone is experiencing this.
