Without having access to your product, I would suggest trying two things.
1. At the point where the pop-up is showing, looking in the Object Browser for that window, and viewing the elements to see if any match the caption you are looking for.
2. During the recording, do a click-and-drag of the mouse as if you were highlighting the test you want for a copy. Then, review the script to see what field it believes the drag occurred on.
If neither of these work, then you will need to make sure your product is compiled for open access, and then you might have to rely on a Regoins.Compare to get the pixels to match rather than the text. For your sake hope it does not get to that point.
I hope this helps!
