Hello Ulises. Maybe I used a poor choice of words when I said "jagged edges". I meant the fill pattern on the branch cuts. Are you saying that version 6 will remove the fill resulting in a clean 3 sector plot of the principle branch with nothing connecting each sector along the branch cuts? I'd like to see that (I'll try and find a machine near me running ver 6 to check it).
