If a problem font is added to one's RISC OS system after Netsurf has established its RUfl_cache file, it seems that on next start-up Netsurf can hang the machine without having given any error information to help diagnose the problem.
When this happened to me, I'd forgotten that I'd added a font (but in any case had not suspected it to be faulty), and it wasn't until I deleted RUfl_cache that the font scanning progress bar could be seen again and therefore where it stopped immediately before the hang. This helped identify the suspect font. Has anyone else had this experience? And could it be considered a bug that Netsurf can stall so unhelpfully during font re-initialisation? -- Bernard
