Hover caption problems

Hi guys and gals,
Don’t know whether anyone has tried out the tutorial for the Hover captions but i created a clip using the captions. All works well except for when i hover over the buttons (they are movie clips), the buttons keep refreshing as if there are layer problems. Its a bit hard to explain but i have posted the swf and the fla on the following link if anyone can help me out with this REALLY annoying problem. Thankyou in advance.
