I have an Excel file with a webbrowser control, linked to a small html site, with an iframe to a government site. We use IE7, and it's been functioning without issue for the last few months.

Today, it has begun throwing an Internet Explorer Script Error:

Line: 47
Char: 4
Error: 'sessionStorage' is undefined
Code: 0

Do you want to keep running scripts on this page?

Opening up the governement site in IE yeilds no error. Opening up the small html site with the iframe yields no error. But opening it up through Excel yields this error on every page.

Any ideas?
