First Post - Navigation Problem

Never tried posting questions before but I thought I would give it a go. I am building a flash + html site and there is a swf embedded in template the pages are based off of. The swf reloads itself every time a new page loads and this causes the image in the banner to be stuck on the “welcome” image. Probably have to visit the site to understand the problem. After clicking any button in the navigation you can see that it begins to load a new image with a dissolve effect but then a new page loads and the original image is back.

Hope that description is not too convoluted.
