The latest oggenc.exe, vorbis.dll and the various oggdrop.exes can be obtained from rjamorim later today at:
http://www.inf.ufpr.br/~rja00/
There is now a C7 version of oggdrop!
This version is definitely not for people of a nervous disposition, with a weak heart or a serious hangover!!
It is a mix of the other 6 with continuous colour change as the fish rotates!! (Contrary to a suggestion I received, I was not on acid at the time!
Have fun.
