Funcs WZ and WG in NB

[Harry Binswanger hb@xxxxxxxx]

The functions WZ and WG seem to have different (and dangerous/bizarre)
meaning in NotaBene, when called within a U2 frame. It might be an issue of
context. I found it is necessary to use TG to restore "Page layout" view
after eXPanded view. (The WZ issue might simply be the familiar
difficulties, even in Xy, with WYSIWYG on some monitors.)
