Dynamic Windows
version 2.4 has been released (8/4/2012). This is a cross-platform
application framework that was designed to make it easy to create
dynamic applications with a modern interface, and was modeled after the
GTK library. A beta 1 release of a new Interface Builder has also been
released, although it seems to include the wrong libxml DLL.
