Problems with buttons in Flash 8

Hi there,

I am having problems with buttons I have created for this website:

www.jamcat.eu

It seems you have to click twice before they work sometimes and also the sound doesnt play everytime you roll-over them.

The buttons were created on a mac in Flash 8 and a sound was placed in the roll-over state of each button with a simple on release behaviour script directing to a new html page.

Any help would be much appreciated.

Thanks!
