Could you please give an idea of the kind of correction you would use if
for? I think of my problem as being unusual because of the nature of the
project and the close quarters... But it's not?

Also, what is the "Panorama Tools" you mention in your last sentence...
Is that the "P" in PTL? Or?

meanwhile, thanks very much for the info...It's all something I've never
heard of and need to study. (I guess you have to read computer
magazines?)
