You're the 2nd person in some hours with the identical issue. I don't understand why as this doesn't normally happen. In fact, you're the only 2 people I'm aware of who have had this issue. I wonder if it's got something to do with recent panther updates.

Did you empty the trash after removing the Java pkg file? I may need to ask some advice about this as I'm not so sure deleting the Java security updates also would be wise.

BTW did you see the sticky at the top of this section about the QuickTime bug issue stopping LW from opening?
