Thumbnail Gallery on Product Detail Page Question

I have setup my thumbnail gallery so when you mouseover each image it uses the tooltip code as used on options to show the color name. See example: [url=“http://shoutkey.com/oriental”]http://shoutkey.com/oriental[/url].



The only problem is if you scroll through all the images once and then start to scroll though a second time the tooltip is way over to the left on the second round of scrolling.



Anyone have any idea how to fix this?
