[Plugin: Google Doc Embedder] Safari Browser on MacBook

Hi. I have the plugin installed on our clients website (http://www.hawkinsmfg.com) on several pages. It is working exactly as it should on every browser except Safari on my MacBook Pro (IOS Mountain Lion). The plugin can be seen in action to display selected pdf documents by clicking on the thumbnail images on the Products Brochures (pdf) page linked on the main navigation (http://www.hawkinsmfg.com/products-brochures-pdf/), or by clicking on any of the dropdown items on this main nav choice. Anything that I can add to make it work on the Mac platform or is this just an issue with Safari on Mountain Lion?

Thank You,
Scott McLaughlin
