did you just update to OS 10.4.6 ? If so, did you download the combo
update ? The other update seems to cause problems. But the combo
update solve them. You’ll find a link to the combo in some previous
messages, if needed.
There is a problem with the X.4.6 update if you did it thru the
"Software Update" OSX feature. You need to load the combo update on
Apple’s website and do the update again.
There are som einfo if you look in the forum’s archives.
