[Javascript] Back button issue

[Teo Petralia]

Hi!
I have a pop-up menu in a form from where the user can select a 
sound. When the user choose the sound that he/she want to hear 
another page is loaded and the quicktime plug-ins play the sound. 
Unfortunately when the user clicking on the Back button comeback to 
the last page the pop-up menu is doesn't show the option selected but 
show the default selected option. This problem arise only when I use 
Internet Explorer. I'm testing on a Macintosh computer.

Does anyone knows what I need to do to avoid this problem?

Thanks in advance

Teo
