Hi, the text edit windows doesn't seem to change anything on the page numbers, whatever the font I choose.
MuseScore 0.9.5 rev 1598
PS actually, it works; here is what I've done: I've been in the menu Style/Style Edition/Numbers. There I've unselected "page numbers", applied (worked), and reselected the same "page numbers". Then apply again, and OK. Then the modifications on the page numbers from the Text style edit window work.
