Copyright field should no longer appear in the new score window
Nightlybuild 3922M Ubuntu 10.04
Although copyright text is now handled as a header/footer, a copyright field remains in the newscore windows.
If you are fool enough to write something in this text adds itself at the beginning or the other one, and cannot be deleted.
I had to do it "by hand" in the mscx file, where I found this text marked-up as "copyright".
