sing C# (and it must be C#), I'm trying to...

1) Create an instance of IE.

2) Intercept the NewWindow2 event of the IE instance created in step #1

3) In the NewWindow2 event processing, create a new IE window.

4) Intercept the BeforeNavigate2 event for the IE window created in step #2.

Everything's working except step #4. The BeforeNavigate2 event handler
doesn't get called when a popup is invoked. (Though I *can* successfully
hook into the BeforeNavigate2 event of the first IE window.)

Ten PayPal dollars and my everlasting gratitude to the first person who
either fixes my error, points me to a patch, or proves that it is a
Frameworks bug. (seriously)

Here's the code:
