Please be more specific. What compiler/environment are you using on Windows?
Did you build gtkmm from source or did you use a binary?

Yes, we have heard about this.

And I just tried it with the Windows gtkmm installer - we can see the
problem in the TreeStore part of the demo.

The people who are using Windows will have to investigate this. It's
probably a problem with the append_column_editable() template. If you don't
want to investigate the problem, then you can use a workaround - just write
the code manually instead of using the template shortcut:
http://cvs.gnome.org/lxr/source/gtkmm-root/gtk-src/treeview.hg#408

Personally, I will not investigate on an unpleasant platform like Windows
until someone pays me to do it.

Please at the least open a bug for this so that people can gradually add
some clues to it.
