Hi there phantomdentist. Thanks for the note on this. I'm actually unable to recreate this in the current code-base on my default 2011 install, though I have had a couple users report it so far.
Here are a few suggestions right off the bat:
* It could be a permalinks-related issue. Resave your permalinks page to reset them.
* Try to identify whether this is a conflict with another plugin. You can do so easily by deactivating any other plugins you've got active and checking whether the issue persists.
* If it isn't a plugin conflict, it may be a theme one. If after deactivating all other plugins the issue persists, please revert to the default 2011 theme and test whether it's an issue there.
If not, is there any chance you have a link to a site where I can check this out?
