Re: Slow Emacs response time

[Jens]

Thanks alot David,

indeed swithcing off syntax highlighting with M-x font-lock-mode RET
makes the problem disappear. I then deleted some big comment blocks
which may have contained math-mode '$' that was never ended - and Emacs
is back in good shape with syntax highligting enabled.

Thanks,
Jens
