Tracy,
This is a known issue with Facebook's Javascript library. It's been reported in the bug report below:
developers.facebook.com/bugs/280811108698311
We recommend using the "Does this repro describe your issue?" link and adding your site to the ones that are affected. We'd also mention you are using JFBConnect, as that may help prioritize things since we work on a lot of sites.
Hope that helps. Unfortunately, there's nothing we can do on our end about this issue, it's completely on Facebook's side.
Thanks,
Alex
