I don't know the specific case of IE7 but I had a similar error with Firefox. This one triggers the onload event before the content is fully loaded. Unfortunately, I couldn't find a solution. So I cunningly used a setTimeout().
This solution is weak but you can use setTimeout(time) with a time that will allow you to load the full content of the document. Warning this time depends on the network connection
