I'm not completely sure, but there have been a series of Windows
updates since the release of SP1. I can't be entirely sure this has
anything to do with this, but I'm willing to guess additional security
measures made by the Windows operating system will cause dialog boxes
to appear on sometimes seemingly innocuous errors.

This is pure speculation though, but if rolling back to the last known
build that works without the dialog boxes on failures doesn't work
then it might be a case of Windows update changing the way things work
for Boost testing inadvertently.

I hope this helps.
