Plugins and Add-ons: Possible to insert interactive video into learning module?

Hi,

I'm trying to use the Interactive Video Reference Plugin but it doesn't seem to work for me:
This is what I would like to achive:
- When answering a question incorrectly the users should be pointed to a certain object in the ILIAS Repository.
This is what I do:
-I've set up a question and I click on "Auswählen" next to: "Feedback Link auf Magazin Objekt bei mindestens einer falschen Antwort". The ILIAS-tree opens and I navigate to the desired object. The problem: As soon as I choose an object from the tree, ILIAS jumps to that object, and I don't get the chance to click on the "Ausführen"-Button!?
When I click on the Back-Button of the Browser I am taken back to the question-editing page.

Is this a bug or something else?

Regards,
Frank
P.S.: When moving the mouse over the "Feedback Link auf Magazin Objekt bei mindestens einer falschen Antwort" the cursor changes to a hand, but a click does not have any effect.
