I test at this time the beta version (5.20) of PB Mac OSX, because in 5.11 I miss many things. I discover in PB 5.20 too, that the fontsize in column views, don't appears in the column titles but only in columntext. The columns titles are hard to read on hi-res Monitors (on NoteBooks-monitors too) and mismatch with the appearance of the other text in the columns, witch can set to a bigger font. The Windows title cannot be changed too, here I miss a possibility to set a font for the whole objects in the window! This is not true in PB beta 5.20 for windows, at least on column titles which can set to desired fontsize. There are a mismatch between PB for Windows and PB for Mac, at least, in opposition as how stated in your FAQ! May be, there are other possibilities, wich I don't knows?
