Thanks for getting back to me so quickly.  Just FYI if you are interested, if you have access to Windows 8 pro or higher, you can get the Windows phone sdk for free (runs on a visual studio express for windows phone install) and access web pages through the emulator.  That's how I am testing, we don't have a windows phone to test on either, we have just gotten a few complaints through our CRM.  Here is the sdk:

The issue is with the front-end pages, we won't need to access the admin section on the phone (so I actually have not even tried), this is purely for the user.  We run a Wordpress multisite with over 250 sites, there are several sites affected, including our main site gsu.edu, you could also check out president.gsu.edu (when I turn either juicebox or media grid off, this site becomes scrollable on the emulator).  I have also tested this extensively on a local installation, because we use some custom themes and my first guess was that there was an issue with our core theme, but testing on my local install with the twentytwelve theme, I get the same result.  If either media grid or juicebox are activated alone, scrolling is fine, but if they are activated together, scrolling breaks.

Sorry, I am not familiar with MP6, is this something I should know about?

Note: Just tried going into the dashboard of president.gsu.edu using the emulator and it seems to scroll without issue.

Thanks
