jsapair,
although not in every instance, if you simply include the coordinates (CTRL-Z) in the screen shot every time then it can be duplicated quite easily to check out what we see in that same exact location.
Usually if you see an object that is blackened out without any textures it is because you are missing either a texture file or more likely have not installed the library that contains those textures.
Can you tell us at what airport the screen shot was taken?
Question 1 = Yes
Question 2 = Yes (see above)
Question 3 = No, Help and Troubleshooting is a better forum for problem reports.
Question 4 = I sure hope not. Letting us know about problems is the only way they will ever get fixed if it is possible to do so.
In your shot I'm not sure what your trying to show with no textures due to it being such a wide view, best to get in close to the offending object and omit the aircraft altogether with a shot from the 2D cockpit without the instrument panel showing. The coordinates will allow us to find the location exactly as I have said above.
