slideshow from iphoto does not show in firefox/safari (only mac mode)

hi there,

i have a problem:

i have created a website in iweb '08 and everything works fine, except the slideshow.

i have exported a slideshow from iphoto as a quicktime file. i have placed this slideshow in my website.

it is shown once only when opened in firefox or safari and then never again. if i change to windows, i have no

problem, it is shown in both firefox (for windows) and IE without any trouble.

does anyone know how i can fix this problem? and why is it mac related but works fine in windows?

i would be soo grateful for any suggestions!

thanks!
