This is the entire screen I'm dealing with; the screenshots I posted for Ira are expanded portions thereof.
That stupid, little iCloud column will not go away no matter what. (I just unchecked it and quit iTunes, and it came back instantly when I relaunched it...same after restarting.)
That particular column is my only problem child; all aspects of all others work as expected.
Thanks for the new library suggestion, but it's not important enough to bother.
