Novell has released a Gtk# Win32 installer for Gtk# 2.12.6, based on the installer source code released by Medsphere.  This is really cool to see more work by Medsphere being integrated into the "upstream" open source communities.

The release announcement: http://lists.ximian.com/pipermail/mono-devel-list/2008-December/030125.html

I will still stress that this is not the officially supported installer or Gtk# version for Medsphere products, and we recommend not using it in a production environment.
