Thank you for writing.
It seems that you are talking about the ControlDefault theme, because the Office 2007 blue theme has not been changed in 2010 Q2 SP2. Yes, we updated the ControlDefault theme to be more consistent with Outlook's, and to be closer to the other controls (we do match the colors of all our themes to ensure this).
Could you provide us a screenshot in order to verify what the issue is with the theme? The screen shot will help us improve the theme, if they have any issues. It will be nice to describe what is the differences with the 2010 Q2 SP1 as well.
I will waiting for your response. Thanks.
