--- Comment #9 from Reinhold reinhold.hoffmann@hotmail.com --- In order to move forward and to have a quick solution we have changed the design of our software from CPropertySheet::DoModal to CPropertySheet::Create which does not show the freezing.
For any further investigation of the issue with CPropertySheet::DoModal please use the archived version saved by Anastasius (see link).
Again, thanks for the support.
