Leaving pages where calendar is initiated in IE9 get error

I have this code working perfectly prior IE9, however i noticed there is a common javascript error when i leaving a page that had calendar object(s) initiated:-

Webpage error details

Message: Object doesn’t support this action

This is how normally the object is initiated at body onload.

myCalendar = new dhtmlXCalendarObject([“calendar”,“calendar2”]);

Any idea?
