These are random crashes, preceded by a black screen. The black screens are not always a crash. Most times Surveyor comes back as if nothing happened.
Is this normal for this build of 2010 ?
Since you've had no responses thus far... You should post information concerning your computer;
Model, Model Number, Processor type and speed, amount of RAM, operating system, and Video Card aka Display Adapter.
This is a problem for some people. What I did to minimize the problem was go into the trainzoptions file in the main Trainz program direction. I made sure that the height and width parameter matched those that you selected under the Options section in the opening screen for Trainz.
It worked for me and some other people as well. For others it did not seem to work.
