I do have exactly the same problem, but I didn't play around with SP3 so far.
I've looked deeply in the most occurrences found through Google, but it
seems a rather new problem. Unfortunately I cannot give you a hint on what
has been changed just before the problem occurred for the first time.
So I'm very interested in the follow up.
