I'm following a on-line course about intellectual property. The professor uses interactive maps or schemes where the themes are displayed. Beside every theme is a plus sign wich opens new content when clicked. The presentation was created with MindManager (Mindjet) but the files are downloadable in PDF, so they can be viewed with Acrobat Reader.
The thing is I've tried with the Ubuntu document viewer and with Okular but all I get is one page that says "click to start Mindjet presentation" and it doesn't work.
Here are the conceptual maps if you need to read the instructions or download them
