I think for making OpenCards more versatile, it should have an option to use formulas as topic too. It seems to me, that it is impossible to use a formula objet as a header.
But this would be a very sophisticated way to use such learning tool for mathematical purposes.
Maybe you can find out how to manage such thing.
You have created a very good peace of software. thanks

You can configure slides to use the slide contents as question and not the slide header. This should do the trick.
To configure a single slide use the slide context menu in the slide pane to open the configuration dialog. If you would like to configure all slides in a flashcard set use the file-context menu in the LTM manager or the "Configure"-button in the last minute session preparation dialog.
ps. Don't forget to share your flashcard sets with the opencards community at http://wiki.opencards.info
