The gtk frontend may be saving itself some time by ignoring scrollbar updates. Try loading the user guide and using the scrollbar to go to the bottom. For me, it only goes partway, and the scrollbar doesn't get updated to allow getting to the real bottom of the document until I click in the document area. It may look fast, but it's still broken ;-) Can you post the output of your profiling? It would be interesting to see which of the painting functions are taking most of the time. John
