Indeed I'm using Powerpoint to make a presentation, syslogd runaway multiple
times a day (~dozen) since i started making my presentation.

syslogd never gave me problem when I was doing other stuff. Previous use of
Powerpoint didn't produced that syslogd runaway so I'm guessing it comes from
either the last 10.5.4 Leopard upgrade or Microsoft Office 2004 upgrade.

-Activity Monitor / Quiting process doesn't work, just stop it temporarily
and it comes back

Any suggestion to stop my Macbook pro getting so hot?
