Javascript menu bug?

[ButtermilkJack]

Just wondering if anyone can help me fix a slight bug on a site I completed a while back?

I've noticed that the main menu 'auto-expands' the "Company" sub-menu when you land on the homepage and I can't figure out why. It doesn't do this if you type index.htm after the domain though (or click on the "Home" button), and it doesn't show the "company.htm" page either, just expands the sub-menu.

Bear in mind I'm a JS novice and just cut'n'pasted the javascript from a free tutorial so don't know where to start?

Thanks!

EDIT: Javascript is here

comment out or remove the following lines in your javascript

this will prevent the auto expansion from happening - if you want to go the other route, and have the expansion happen either way, let me know

            if(aTags[no].href.indexOf(fileNameThis)>=0 && aTags[no].href.charAt(aTags[no].href.length-1)!='#'){                
                if(aTags[no].parentNode.parentNode){                                
                    var parentObj = aTags[no].parentNode.parentNode.parentNode;
                    var a = parentObj.getElementsByTagName('A')[0];
                    if(a.id && !activeMenuLink){
                        
                        activeMenuLink = aTags[no];
                        activeMenuItem = a.id;
                    }
                }
            }
