CD11. IDrawShape::CreateDropShadow works incorrect...

Hello.

I call CreateDropShadow in my application written in MSVC2K3 and receive strange results. Method does not return an error. But in CD's object browser no drop shadow object. And Interactive Drop Shadow Tool shows that a drop shadow object already created with my parameters. I call CreateDropShadow like this:

Application->ActiveShape->CreateDropShadow
(
cdrDropShadowFlat,
70,
2,
0.75,
-0.75,
Application->CreateRGBColor(0, 0, 0),
cdrFeatherAverage,
cdrEdgeLinear,
0.0,
0.0,
0
);

What mistake I do?

Thanks.
