byork,

 

Looking at a number of threads, I have noticed users experiencing weird behavior.....I hope this helps!

 

Here is an excerpt out of the PMDG Intro Manual you may find useful (starting page 0.00.21):

 

"KNOWN FSX’isms TO AVOID

The best way to think of the PMDG 737NGX is to approach it in terms of

a stand-alone simulation that is using your FSX installation in order to

provide a world in which to simulate the 737’s flight operation.

We have put a tremendous amount of time and energy into make certain

that this experience is as seamless as possible, but occasionally we find

unintended consequences of our efforts to provide you with the most

accurate simulation possible.

A few notes to keep you from running into trouble:

 

• There is a common misconception that when loading a complex

simulation like the PMDG 737NGX that you should first load the

default Cessna into the simulator, then load the PMDG 737NGX.

This is not a factual conception and in fact we do not recommend

the practice at all. What is required however is for the default

Ultralight at Friday Harbor to be your default startup state in FSX.

 

• One shortcoming of all PMDG products for FSX is that our

products do not like to be “re-loaded” on top of themselves. This

means that if you have one livery or variant of the airplane

selected and running within the simulation world (say, a 737-800

with winglets) and you wish to change liveries to a different 737-

800 with winglets, you will need to shut down the simulator and

then select the new variant or livery you wish to switch to from

scratch. If you load an NGX livery or variant on top of itself you

will see strange issues in the cockpit, FSX may CTD or otherwise

crash etc.

 

• Setting the PMDG 737NGX as your default flight can cause the

same behavior described above from reloading it on top of itself.

The default flight is loaded in the background as you start FSX

and thus if the NGX is your default flight and you then select

another variant, it loads on top of itself even though you may not

actually see it happen. Keep the default flight as the ultralight at

Friday Harbor and you won’t have any issues with this."

Thanks for sharing that, Bill.

 

I've been preaching that for ages!
 

Although this is the accepted way, I must say that after 9 months with the 737ng and FS2 crew, I can have the 737NG as my default load with no problems whatsoever.

The only caveat is to load with the 2d cockpit and then change to VC.

You are right though about reloading on top of itself. I find I have to load something silly and easy, like a Bell heli and then load another PMDG variant for it to work properly.

 

Just my 2cents worth!

That's very possible.  Computers and FSX, like people, don't always behave the same way.

 

Important thing is it works for you.
