Re: A question about RegionFunction in ver. 6.0

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).

Thanks!
