My presentation has a slideshow, and when I upgraded it to the newest version of Powerpoint, it doesn't work how I intended it anymore.

The slideshow starts when you click on a link in the first slide, and it runs (loops) until you click Escape.
In the old version of Powerpoint, you just went back to the first slide, in presentation mode, but in the new Powerpoint version you exit the presentation itself as well.

Maybe I have to configure something somewhere I don't know about. Anybody that can help me?
