Flash Movie doesn't work under some Netscape Broswer

Hi guys:
I am kind of new to this website and I have run into this problem recently.

I made a flash opeing page using Flash5 as index.html and I saved my work as Flash 5. It works perfectly in the all IE and most Netscape , but doesn't work under SOME netscape such as 4.6.(I use 4.76). The problem is that the movie will keep looping and some button will display in a funny way.

So I saved it as Flash4 format and at a certain moment, it worked. But when I add somethng else in my movie, it doesn't work again no matte what kind of format I save it.

Does anyone can give me some solution for my problem?

Thanks.
