I have a similar problem – the pause button on the tutorials on the intro page (e.g. the Java EE 5 Development flash animation) doesn’t seem to work, which makes it quite painful to try and follow through the same steps).
While there is a pause button; I can’t seem to pause the animation – I can only jump forward/backward to different stages of the intro; and I have the same problem both on my Mac and Linux boxes…
Any idea why the pause button doesn’t seem to react? Or how I might be able to pause it?
