Dropdown Boxes stuck open in IE7

Hello all:

If I edit this line of code in my .js file, will it solve the problem?

“{
this.ver=navigator.appVersion;this.agent=navigator.userAgent;this.dom=Y7.getElementById?1:0;this.opera5=this.agent.indexOf(“Opera 5”)>-1;this.ie5=(this.ver.indexOf(“MSIE 5”)>-1 && this.dom && !this.opera5)?1:0;this.ie6=(this.ver.indexOf(“MSIE 6”)>-1 && this.dom && !this.opera5)?1:0;this.ie4=(Y7.all && !this.dom && !this.opera5)?1:0;this.ie=this.ie4||this.ie5||this.ie6;this.mac=this.agent.indexOf(“Mac”)>-1;this.ns6=(this.dom && parseInt(this.ver)>=5)?1:0;this.ns4=(Y7.layers && !this.dom)?1:0;this.BWD=(this.ie6||this.ie5||this.ie4||this.ns4||this.ns6||this.opera5);return this
}”

And, what exactly should I add?

Thanks!
