Typical case: C-h s (that is, view the syntax table), and scroll through it, and it can take seconds for the screen to do something after C-v It is possible this is only happening if there are loads of "unusual" Unicode characters in the buffer in question. I don't have any good very long files of lots of Unicode characters to check if it is happening on all buffers, or just *Help* buffers. Is this a known problem? Should I file a bug report? -- Perry E. Metzger perry@piermont.com
