Please Help Me With This Flash Bug

Hi everyone!

I was wondering if anyone out there has ever had this problem with their flash navigation:

My site, continues to have problems with about 25% of the users that come on the site. The top flash navigation links do not work for them. One of the users whom reported this was using Mac OSX with the latest firefox. Could it be something wrong in the htaccess file? I noticed when I visit notice there is no www … in internet explorer 7 only, I too am unable to click on the links.

Any help on this would be greatly appreciated.

Thank You!
