Me too... but I don't think there's a redrawing of the cat page, really. What seems to be happening is that M-x man RET dog RET pops up a "*Man dog*" buffer in a window, and then starts working in the background. And then it can't find the dog man page, and then kills the buffer (and window). This makes everything redisplay, which is the blink we're seeing. I'm not sure whether anything can be done about this -- it's an artefact of working asynchronously, and then restoring window configurations. Anybody got any ideas? -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
