I have a CView derived class that uses a bitmap to blt the view for flicker free operation.

When I use the default Print-Preview, all is well.

When I use your Print-Preview, the new menu you add is under the bitmap of my view, so it is not displayed, unelss I hover over a button, and then it is displayed and flickers until I leave the area...

How does your CExtPPVW support such design, and if not, please solve this problem.

The CDrawView class in the DRAWCLI sample demonstrates how to use the CExtPPVW template class with MFC’s document/view architecture. Please also ensure you applied WS_CLIPCHILDREN|WS_CLIPSIBLINGS to your view window.
