There seems to be a lot of speculation out there, but I can't find anything about this issue on the Microsoft website. Anyone else having the same problem?
My SP2 just went on a few days ago and I haven't tried to capture anything yet. I may have to do that when I get home. You might want to try giving a call to the SP2 phone number the guy mentioned in the message thread you posted. Since that thread was about a month old, perhaps MS knows what's going on by now.
The US phone number for free SP2 support is (888) SP2-HELP (772-4357).
