media manager problem

[sfmammamia]

I have been following the steps in the following tutorial to set up downloadable music with previews:

I have set up a Media Collection and uploaded a clip. It's showing as available.

I've created a music product in the correct category and uploaded the MP3 into the downloads directory. It's showing correctly in the Downloads Manager.

The attributes for the product are set to "Download."

However, when I return to Media Manager and click the button "assign to product", I get a message "No products in this category".

Any suggestions?

I figured this out, and am documenting in case it's useful to anyone else who runs into this problem.

When I selected another product category from the dropdown menu in the media manager, and then returned to the product category that I wanted, I was able to complete the process of assigning the products.

Definitely not intuitive.
