Some Jess features are accidentally unavailable in the binary-only
demo distribution. 6.0a7 was the first version of Jess released in
this format, so we've been learning a few things about how to do it
correctly. I'm going to be releasing a 6.0a8 version very soon with
minor bug fixes to correct the situation.
If you have the licensed distribution of Jess, these problems don't
apply.
