Not too sure.  I'm a bit of a gtkmm "newbie" also.  I'd repost your question
to the list if you still need help.

I get many "Gtk-CRITICAL" messages in my application and it works fine
so.....

Hi.  Thanks, that did help.  I allow the user to push a button which calls
a function that contains all the selection code.  When the user pushes the
button, this gets outputed:

(mrmgui:16041): Gtk-CRITICAL **: file gtktreeselection.c: line 360
(gtk_tree_selection_get_selected): assertion `selection->type !=
GTK_SELECTION_MULTIPLE' failed

Can you explain this?

Thanks,
Michael
