Haveing problem embedding Win Form control in IE with managed C++ assembly.

I have been trying to embed a C# .NET Windows Forms User Control into IE
using the <object> tag with a dependency on a managed C++ assembly. I
basically wrote a very simple test control in C# that has a button that
calls into a managed C++ assembly that just returns a string object.

The control works fine until I try to call into the managed C++ assembly
from within the C# User Control. When the call is made, I get an exception
that appears to be security related. I tried turning off CAS security using
CasPol -s off, but I still get the exception (see below). Why can't I call
a managed C++ assembly from within my control? I have checked directory
permissions and dependencies and everything seems to be in order.

I would really like to get this to work, but the Managed C++ dependency
(which I need to have) is really impeding my progress to get this to work.
