However, I am puzzled as I take a few snapshots of a big area and they

same number of atoms, nothing changed. Instead of using about 100 Mb of 
memory during the image acquisition it used over 400 and crashed the

machine with 4Gb of memory, but right now I am just trying to finish up 

How do I take somewhat lower res pictures off the screen?????????

As to the two transparent models, this is important and needs to work 
consistently. But knowing about it allows one to try and work around the 
problem.....argh. But I am not sure the ID number is the whole story,
