I'm continuing the RUDL development log here, the original is at http://froukepc.dhs.org/rudl/log.html
Fixed the problems:
.type has been changed to .class everywhere (solved deprecations and disappearing windows)
Some occurrences of ".6" have been changed to "0.6" since Ruby complained about it.
Now I have to get back in synch with SourceForge CVS, and rebuild the packaging script... *sigh*
