How to deal with events/callbacks from something that appears to be on an MTA thread.

I am writing code with Visual Studio 2010 in VB.net with a WPF project.  I have added references to MSHTML and SHDocvw as I am automating an Internet Explorer window.  Note I am not hosting the webbrowser on a form.  I am currently using the Shdocvw.InternetExplorer class to do this.

Irrespective of whether it is this class or another I assume my questions is a Managed Code / unmanaged code problem.

I am using WithEvents for my events.  The problem is that I must use an STA thread to for example do anything with MSHTML but the events that come back from Internet Explorer are MTA threads.  To work around this I have used a dispatcher, but this is not I think the best solution and I am thinking there must be a better way.  This whole COM / Managed / Unmanaged code is a little bit hard to come to grips with as there are too many options.

So what is the correct way of dealing with the events raised?
