A further observation - now running 10657. When first loaded NetSurf responds normally to the scroll wheel, but after a viewing as few simple pages and scrolling them it exhibits the same hanging problem.
I upgraded to 10657, ran NetSurf, went to ROOL and scrolled up and down the ROOL homepage without problems several times. Went to riscos.info home page and after a few scrolls the response got worse. Not sure if this is time-related, activity-related or something else. Would a log file help at all? -- Grahame Parish
