[F8] Movie doesnt load right on a MAC! Help please

[reedy2k]

I have a flash movie which uses an external xml file to load in some thumbnails and large images like a gallery

My client has reported that on their MAC in both safari and firefox that the flash movie loads but the thumbnails do not work, their rollover effect doesn't happen and when clicked nothing happens

Yet when they visit another page of the site and then return it does work

Its all fine on browsers on a PC, I don't know where to start troubleshooting this
Any ideas where to look? Possible known issues?

Thanks alot

perhaps something to do with the way you preload the thumbs? can u post your loader code?
