Error Using Webbrowser Control on Form

[Selden McCabe]

I'm trying to display some HTML on a form in a VB.Net project.
I've referenced the COM WebBrowser control, and put an instance of it on my
form.

But during the Form_Load, I'm getting the following error:

The code generator inserted the following line of code in the form (wbReport
is the
name of the WebBrowser control)

CType(Me.wbReport, System.ComponentModel.ISupportInitialize).EndInit( )

When the form gets loaded, this line of code generates a
InteropServices.ComException
("Unknown Error").

This is driving me crazy, since I downloaded a simple example of using the
WebBrowser in
VB.Net, and it works without this error.

A couple of points:
The webbrowser control is hosted on a Tab control, which is on a form that
is an MDI Child.
Could either of these be the culprit?

How can I display HTML on a form in VB.Net?

Thanks!
