1. While trying to learn how to define a moderately complex adverb, I have
several times received a 409 error, telling me that my server is not
responding.  After some experimentation, with restarts, I have found a short
sequence which leads to the crash:

J Http Server
   JVERSION
Engine: j701/2011-01-10/11:25
Library: 7.01.040
Platform: Darwin 32
Installer: j701a_mac_intel.dmg
InstallPath: /Applications/j701

   13!:0 ] 1
   negx=: 1 : '(- x) u y'
   3+negx 7
|domain error: negx
|negx[:0]
      negx=: (3 : 'u - y') : (4 : '(- x) u y')
   3+negx 7

The second definition entry should have reported a Stack Error.  When Debug is
off, the second usage attempt reports a Value Error for u, without killing the
server.

2. I see that my copy of the software is over a year old.  It is not easy to
find release dates on the Downloads site;  additional columns for engine and
library dates would be most useful.  If this problem has been fixed, I 
would be
happy to update.

3. Dictionary sections on Monad-Dyad use are terribly brief.  Discussions of
adverb and conjunction definition processes are longer in JLearn and JfC, and
somewhat complement each other, but still leave me somewhat confused.  Are
there yet other elaborations available?

Thanks.
