There were several issues with HAST that have been fixed in CURRENT and MFCed
to STABLE. So, I would recommend starting from upgrading to STABLE and
reporting back if you still have the issue. Note, there is still a known
problem in STABLE that has been fixed in CURRENT (r223181) but is not MFCed
yet. I am going to MFC it soon.
