We're planning to look into this in a few hours. We have not logged into your administrator area or made any changes to your site yet, so if there is odd behavior happening, it's not from any changes we've made.
We'll let you know what we find when we get in. I'd recommend taking a backup of the site now, just in case something bad is happening there.. we don't want to change the behavior, and I'd hate for things to get worse.
Thanks,
Alex
