Hi ian092488, is the problem with a web application extracting this data through the browser? Do you notice a difference between Firefox and other browsers on the Windows 7 system (e.g., IE 11, Chrome)?

If this is not a Firefox/web app issue, there probably are more appropriate forums for your question.
