Hi george -

Sorry - I meant 'fixes' when I said 'securities', but here is what I was referring to...

The initial release of Service Pack 2 (11.0.5058) does not contain the fixes from Service Pack 1 Cumulative Update #10 or #11. So, if you install SP2, you need to understand that you will lose those fixes unless you subsequently apply at least SP2 Cumulative Update #2.
