Try closing IE and restarting it. We're definitely seeing an improvement, so I think it's gone, but obviously, I could be wrong.
As for upgrading the modules, it's not that bad
In the admininistrator area of your site, if you go to Components->JFBConnect, you'll be on the Overview area of JFBConnect. Here, we have a section that shows you the versions of each of the JFBConnect pieces, and what version you have. You'll see a few numbers in red.. these are out of date and should be upgraded.
To do so, simply go to My Subscriptions area here on SourceCoast, grab the latest jfbc_modules zip file, unzip that file, and use the Joomla Installer to install each one. That will automatically upgrade each module as you install it.
Hope that helps, and keep us posted!
