@Gary, thanks for the source notebook. I evaluated it and used the export wizard to embed the result, and it all works just fine, exactly like my previous examples show. I can only restate that the particular problem you are seeing with mismatched object size settings is likely do having exported from a notebook that was magnified.
The NB you attach here does not have such a setting, but the results you show on your site are exactly what you would see in the magnified source notebook scenario, i.e., the object size values in your embed code ('Log.function.emball150.cdf', 646, 508) are precisely the numbers you get when magnifying the notebook to 150%. I have a hard time believing your issue is anything other than this, and you should simply run the export wizard with the notebook at 100% and recopy/repaste the embed code for your page.
At this point, since I can't reproduce a problem with your content, I think you might have to pursue this directly with tech support to see if there is some other anomaly at play here (which I can't currently think of). Sorry I can't be more help on this particular point.
