Clipboard from Office 2000 with Delphi 5

I use Delphi 5 on two PC's one with Window 95 and
Office 95 and one with Windows NT 4.0 and Office
2000 installed.
On the NT Machine the Function
Image.pastefromclipboard does produce always a
error even with the Delphi Demo "Graphex.exe"
see: delphi5\demos\Doc\Graphex

I suppose it has something to do with the
new function under Office 2000 to have up
to 12 different Clipboard entrys.

Do you have a solution.
