Launching this app brings up a window called Coleccion.

Clicking the Data tab shows:

Fecha de creacion
Fecha de modificacion
Numero de elementos

Opening the Preferences and selecting the General tab, strange word "Dinstance"

I created a test file with one field - large text. Then created a new item. in the main window there are two panels - one with the collection (looks like a blue book) and the other with fields contained in the collection. The text I typed looks fine but below it there is this:

{NSFont = "Helvetica 12.00 pt. P [] (0x1ad50a60) fobj=0x0037dc20, spc=3.33";}

If you had a contact email or web form I'd be happy to send these outside of Version Tracker.
