Hi Wayne,

I did not really have a look into the code, but I encountered an issue
in DIALOG_EDIT_COMPONENT_IN_LIBRARY dialog: the page 0 is incorrectly
drawn (the page 1 is drawn as background of page 0).

Attached a patch that fixes this issue (already encountered in
simulation options frame).

To remove a page from a wxNotebook, using Hide() is incorrect: one can
hide a widget inside a page, not the page itself.
(RemovePage must be used instead)

Hide() the panel can work on some platforms, but not all.
Moreover Show() the panel draws this panel in the background of the
active panel!
Strange result...

Thanks.
