Firefox20: 'Action Items' slide broken

[tomByrer]

This is more for a FYI as you develop TweenDeck: Seems to happen only if I use [PageDown] instead of [->] key, only on this slide, & only in FireFox20 & not Chrome Canary. If I go backwards though this slide, it seems to work as expected.

Feel free to close, as this is more for a record for future issues that might come up.

Thanks for an exciting slideshow system!
