I must be heavily cached somewhere. I'l cleared my browser cache, deleted the IOD cache file on the server, and I still have the little square box. When I run the file like you suggested, it works fine. So it must be somewhere (Comcast probably) that has something cached still. Plus it's all four browsers that I can try. I'll check it later and see.
This happens a lot, when I make changes to a page, often I can't see the change for a while.
