Importing PowerPoint slides: Cannot select which file to import
The first time I tried to import PowerPoint slides, I had no problem. From the Captivate file I was working on, I went to File > Import > PowerPoint Slides... , I was prompted to select a PowerPoint file, and then I was given the option to select all, or some of the slides from the PowerPoint file. Great.
The problem:
Later, while working with the same Captivate file, I needed to import slides from another PowerPoint file. Again I went to File > Import > PowerPoint Slides... . However, I was not prompted to select a PowerPoint file. Instead, this is the window that opened:

The PowerPoint file is already selected for me. But I don't need to import more slides from this PowerPoint file. I need to import slides from another one.
However, I see no option to select another PowerPoint file.
What can I do now?
