OK, the CI system just built #740 with a spidermonkey 1.8.5 library with the JIT disabled as suggested by Chris Gransden. Can this be tried by someone with access to RISC OS? and please be aware this may well behave very badly indeed.
If this fails I have now successfully built 1.7.0 for RISC OS (though not run tested) so the possibility of using an older known working version exists. Please remember to enable javascript via the nice shiny new configuration interface Steve Fryatt has provided. -- Regards Vincent http://www.kyllikki.org/
