This is a problem that I have been experiencing today: when I press on the scrolling arrows at the right bottom of the floating window (in paged view), sometimes the view reverts to normal (not paged). When this happens, the "paged view" option is still showing checked on. When I uncheck, there is actually a sort of visible change in the font size but not in the columns. When I recheck it then it sets the text in columns again.
