The C++ Window objects are normally deleted when their parent is
closed/deleted.  Tn the case of wxNotebook calling DeletePage will also
delete the C++ window object while RemovePage will not.  Usually when the
C++ object is deleted the Python object will be too, unless of course if you
are holding extra references to it or there is a circular reference
somewhere.

Try reducing your app to a as small as possible sample that has the same
problem and perhaps you will discover the cause of the problem along the
way.  If not then you have something to share with others so they can help
you track it down.

I don't think I've seen anything to generically go straight from a grid to
the printer, but perhaps you could dump your grid data to HTML using table
tags and use the wxHtmlEasyPrinting class to print it.

If this won't cut it for you then perhaps you should ask on the
wxPython-users list to see if anybody has some ready made code for you,
since these really aren't Boa questions.
