problem with flash buttons

Hi

I have downloaded two flash templates(3, 4 in the order). I have customize the pages. If one page wants scroll down the flash buttons freezed.The roll over efe doesn't play. You have to click two times on the button to open new page. This problem is only with firefox. I have 3.5 version. With IE everything is fine.
go to http://www.danisoft.gr/alextest/ at "PRODUCTS" page and scroll down, then scroll up and try to click buttons

thanks in advance

Hi,
Firefox freeze because the images you add on page test2.html are too heavy. For example button1.png weighs 248 Ko, it's far too much !
You should reduce the wieght of all your images and use .jpg files for these kind of images.

I make all the images jpg and nothing happens. I added some <br> at the page "SOLUTIONS". This page is the default.The problem stil exists http://www.danisoft.gr/alextest/
