Hi Tom,
Option one worked when I added a new slide but I really wanted to keep the interaction on one slide without the user having to click to another slide before going back to replay the interaction.
Option two worked in terms of moving the rocket to the right place - but it's still facing the wrong way and carries on facing the wrong way even when it moves along the originl motion path (after the reply buttin is clicked) it's as if it's recogising the rocket as being a new object that faces a different way, weirdly if you click the 'blast off' button before it reaches the first hot spot (which hides the 'blast off' button) it makes the rocket turn turn around with each click
