Can you add annotations using an AcroAVDoc when opened using OpenInWindowEx?

Question

I am writing a C# application in which users will need to annotate documents. I would prefer to use Acrobat's standard annotation tools (and toolbar). I am currently using the command OpenInWindowEx(filename, handle, AVOpenParams.AV_EXTERNAL_VIEW, ...) (of an AcroAVDoc object) to open a PDF in a window that my application can control. Unfortunately I cannot seem to get the annotation tools to display. In fact, the whole thing appears to be read only (with the exception of e-sigs). When using just the Open command of an AcroAVDoc the file opens in Acrobat and behaves as expected, but then I cannot resize the window or move it with the other windows of the application.

All,
I moved the project from .NET 3 to .NET 4 to take advantage of dynamic objects, and hoped to be able to use the same type of syntax as one can use in VB.NET to work with the JSObject. Unfortunately, no matter what I try, I get the exception "Value does not fall within the expected range." Can anyone advise on whether we can use dynamic objects?
Example:
AcroPDDoc pddoc = new AcroPDDoc();
pddoc.Open("C:\\test.pdf");
dynamic jso = pddoc.GetJSObject();
jso.Collab.showAnnotToolsWhenNoCollab = true; // or jso.console.Show(); it doesn't matter anything seems to throw the exception
Thanks,
