A problem I see:
Expected end of value for property but found ':'. Error in parsing value for property 'background'. Declaration dropped.
[Break on this error] undefined
widgets.css (line 15)
Another, possibly related, issue:
The status of the page continuously says "Transferring data from flash.quantserve.com..." and never finishes loading. Not only is this a drain on resources, it is also a yellow flag to your users.
Perhaps as nice as the widget is, it could use some tweaking, or you could possibly do without it. A visual problem with it is that it's not wide enough. If you scroll all the way over, the scrollbar goes beyond the borders and you can't get it back. I would say do without the widget, but if you need it, it would definitely be something to look at.
However, the ultimate visual problem is what I said before, your page starts too low. You could reduce the image of the phone to make space or even start your content in divheader. If you really want to keep it that size, possibly angle it to get just a little more space in your page. I'm viewing at 1280x1024, which is definitely larger than the average, but just to get to your widget you have to scroll about 3 page lengths.
Additionally, I did some more detailed testing on your widget. There's an iframe there, in the iframe you should set the width to 215. This will solve the scrollbar problem. You may also have to resize the parent DIVs as well, however, I didn't need to in Firefox.
I hope this helps,
