>As a side note, I previously tried retrieving the window handle using the GetTopWindow API call in the form's Activate event. Surprisingly, the window handles for the two elements of the array were identical. I'd like someone to explain that one to me.

If the handles are the same, they are both for the same window (different windows have always different handles). In this case (probably) when the Activate event occurs, the window is not "on top" yet. So, the handle is not for the current form.
