We've been bitten by a number of Gtk bugs over the years. These particularly affect our Windows packages, where we have traditionally had a limited set of prebuilt versions of Gtk to choose from, and had to choose which bug we ship with. (These days we've given up on the official releases, and build our own Gtk.) These tables cover the versions of Gtk itself, since that's what we seem to have trouble with, rather than its dependencies like Glib. (Newer versions of Glib tend to drop compatibility with obsolete versions of Windows; this isn't covered here.)
