You have probably seen the mail already, but I have sent you an example of the method I discussed above.
At the start of the movie the animation is stopped (stop action in frame one)
Create a hotspot (invisible button) covering the movie area by making a shape into a button and editing the button so that the shape is only in the last frame - the hit area
Create another movie clip on main time line with a tooltip 'over' and 'out' animation states using frame labels (with stop action in first frame) - this is built so the tooltop appears when the mouse in over the hotstop. Give this an instance name. (in example code below, it is called 'tooltipMovie'
Then on the hotspot (invisible button) add the following actions:
this.tooltipMovie.gotoAndPlay("over"); // these are telling flash to go into the movie with the instance name tooltopMovie and play the relevant frame label, in this case "over" //
gotoAndPlay("play"); //this is the frame label on the main time line called play //
Finally, to check how frame labels and instance names are insterted, select one of these items and then check the property inspector to see where/how this has been added
Hope this helps..
Extra: it is also possible to do away with the hotspot and add the mouse actions to the MovieClip as movie clips also take mouse actions, but this would mean changing the code slightly... I still use hotspots as I find them quite flexible for what I need
