Apparently, not only does OOo-3 break python, it also dis-innovates with presentation layouts. One of the advantages that OOo used to have was to allow you to print handouts on an otherwise blank page. This allowed plenty of room for taking notes, especially if one moved the slides a little away from their starting points. OOo-3 apparently “improves” on this by mimicking MS Office’s stupid note taking lines. As far as I can tell they are surgically implanted, unable to be removed. So now my handouts are useless to me because the lines are the wrong size for me to write on and take up all the note taking space.
So this is now the second time I am rolling back from OOo-3. Each time my experience of it has survived less than a day.
