see, those would be my first thoughts as well. that's when it's expected to happen and when usually it would--when i was making my computer work hard. but today... nothing. i've shut down everything, and it just keeps spinning. i mean, it'll stop for a few minutes, but then start right back up again with no provocation. not to mention that it started this when the only things i had running were safari and msn messenger... not exactly a big workload. i turned off all of the sharing prefs too, just in case and still. grr. not happy. all i can think is that it has something to do with the new system updates. if so, it should pop up on caucus soon (i hope). if not, then i keep trying to figure it out.
