Mirek,

tried out your latest advice, size of accepted data does not match size of BITMAPINFO struct (data.GetCount() == 0):

* C:\upp\out\examples\MSC9.Debug.Debug_Full.Gui.Mt\UWord.exe 23.01.2015 16:02:45, user: admin
DIB accepted

Just a few Side Comments:
Maybe it's something specific to my Win8.1 installation after all. This time I also did a few tests dragging jpg from MS Word into both LibreOffice and OpenOffice Writer and they failed too, showing only blank img frames over a doc background.
Both LibreOffice and OpenOffice show context menu options to dialogs to manipulate imgs when you right-click on img frame icon. These dialog boxes however show copies of the DnDropped img thumbs, which they save in a TMP file. So I'm confused: how come the img can't be shown on document while they save and show it correctly from a TMP file?

Thank you once more, for your patience!
