Apple will have to rush out another update
I see 3.2.10 coming out VERY quickly after all this.
So far, we've had broken java, broken safari, trashed external hard drives.
Apple has dealt with breaking external drives before, but breaking java and breaking safari are not small things.
3.2.8 had many small problems but nothing serious. (for me, fickering of my pb backlight was the worse, I simply turned off the light autosensing, and accepted that my pb was a little less cool for a while..

now fixed in 10.3.9
3.2.7 seems to have been the best one so far....
My experience with 10..3.9.... (15" PB 1.5ghz) ... repaired everything with stermachine both before and after downloading.
Got blue screen of death when rebooting. EEK!
Yes, a blank featureless expanse of blue (with a mouse pointer that responded to trackpad input) on my laptop eek!!
After 10 mins, still blue, so rebooted.
Came up fine phew! Noticed that now the top menu takes an age to load when booting. Top righthand menubar icons (clock etc) are drawn way before the menu bar loads, making my powerbook look like some kind of borked windows machine

( for a few seconds / half a minute anyway)
Java - hmm broken huh.
Rebooted, repaired permissions, prebinding etc. still broken.
Dowloaded the security update and rebooted (again!) Java working fine now.
Normally use firefox, but after reading this thread, gave safari a go.
Wow, starts instantly! Like magic! But crashes when exiting. Twice so far.
Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_INVALID_ADDRESS (0x0001) at 0x77656276
Hmm. Borked. This update has its good points, but Apple have bodged up in other places.
Expect to see a new update PDQ.
