When I'm on the post/edit page in the admin section, and I click on the drop-down to sort by category, the space is there for all my cats in the drop down, and I can select them, but they are invisible! In other words, I have to select the category blindly. If I know the whole list by heart and know by counting down each blank space in notches to bring up the posts specific to that category, I'm fine. But I would like to be able to see what I am choosing. Funny that way... :-P
Let me know if you have a fix?
