Previously, a beam, column and concept mode file opened simultaneously would share the same set of settings; and if one was opened when another was already open, the program would ask which set of settings would be used for all of the open files. A file saved at this point would possibly have its settings permanently altered by the ones from another open file.
As the program now allows many files to be open, and these files to be all part of a single project, the program allows all but the company settings (and Project if a project file is open) to be unique to each file. Then when a setting is changed, it applies to the currently selected file only.
