add item to webbrowser right click menu

Question

Hi all
I am creating an application using the webbrowser1 control. Is there a way to add the item "Copy Link to Textbox" to the default right click menu shown when the browser is running. I'd like it to copy the link to a textbox named txtNewWindowLink. Ideally, this item should be added at runtime and deleted when the application is stopped. I don't really want to create a custom right click menu as I'd still like to have the "Save Target As" option available.
I'm not sure if this is even possible but any help is greatly appreciated.
regards
Colin
