Hi Dan,
It is good that you and little old me posted it here on two occasions, because there are whole armies of non-computer-savvy users that forget to update Java to the most recent and fully patched version.
It is fortunate that Java with the new installer also removes the oldies (vulnerable versions and exploits always seeks out those that are vulnerable!), so they have no excuse now when we find older versions of Java on their boxes, and I have Secunia PSI version 1.0.0.4. here...
