I have NO IDEA why IE would choke on the void call and insist that it is ‘insecure’ content, but that’s what it seems to be doing. I think. I admit that I do not understand this. The fix works in IE 6 and IE 8 (have not tested 7 yet, no reason to believe it would not work).
Perhaps someone can clarify why this is happening, and what a more elegant solution would be?
