It is. `special-display-popup-frame', for whatever reason, has (set-window-dedicated-p (frame-selected-window frame) t) so C-a and C-n are not allowed to use the help window because they do not put their information into *Help*. > One way to work around that is to restrict help-for-help to the > original frame in some way.

It doesn't seem right that a > help command will display differently when you run it through > help-for-help. We'd have to write our own `special-display-function' for that. martin
