When I attempt to add a new category using the steps outlined in your help section, after clicking OK, the newly created category disappears, and does not show up, even after closing the program and reloading.
I'm using Personal Edition 1.2, downloaded today, 2/25/04. I will keep on the lookout for the updated release. If all go well I will upgrade to the Advanced version!
Very nice reader (still like folder views, though!)
