OK, I posted a new build of Topicalla. It's better in some ways and worse in others. It's better in that it has a better template parser. It's worse in that listboxes often get messed up and the search fields don't work. This version works on Mozilla 1.5b and the latest nightly builds of Mozilla Firebird. There seems to be some string library incompatibility for Mozilla 1.4 and earlier so it only works there for 1.6 seconds before crashing. I'll work on that issue next.
The main point of this release is that I've also included a command line ReoPath interpreter. It still uses Mozilla libraries though but you can load datasources and execute expressions from the command line. It doesn't currently work for remote RDF, so you'll need to file or chrome URLs.
