general probs you may encounter:

 sometimes the demo loops round and restarts when it should have quit, don't
ask me why it pisses me off too.

 the demo redefines space to be escape - it should always reset it when it
quits for whatever reason but if it doesn't, just type: " *fx220,27 " at the
command line.

 'too many nested structures' comes up every so often in the rave demo, don't
know why but its got better recently so just restart if that happens.

 can't be bothered to read the scrolltexts as they scroll by? they're all
normal text files inside the relevant bits of demo so you could load them
into !edit if you wanted, honestly it's worth it!
