Hi Martin,
I do not have much help for the odd behavior with the UI, except to
say that occasionally I've found it helpful to clear the browser cache
for such things.
I can address the issue with the environment variable. There is an
inconsistency between LAS configure.pl and the most recent Ferret
release, v7.2 which doesn't use PLOTFONTS but instead looks for the
environment variable FER_FONTS. (This will be corrected in the next
Ferret release.)
LAS v8.6.1 will work well with Ferret v7.1, so that is our
recommendation.
Or you could edit both FerretBackendConfig.xml and FerretConfig.xml to
include both FER_FONTS and PLOTFONTS.
<variable>
<name>FER_FONTS</name>
<value>/home/users/tmap/ferret/rhel6-x86_64-linux/ppl/fonts</value>
</variable>
<variable>
<name>PLOTFONTS</name>
<value>/home/users/tmap/ferret/rhel6-x86_64-linux/ppl/fonts</value>
</variable>
The closing tag should be </application>. FerretBackendConfig.xml and
FerretConfig.xml are both needed. They are created when you run
configure.

The LAS browser output never finishes and cannot be cancelled. In
las.log:
LAS http-apr-8080-exec-2 ERROR server.LASAction - Illegal request
parameter value.
LAS http-apr-8080-exec-2 ERROR server.LASAction - Request contains a
parameter value that is not allowed.
