I'm using version 3.0.1 and when I add a new category through the 'Categories menu' in the dashboard it doesn't automatically update the categories list. The only way for it to appear is if I go out of the page and then go back in. The same happens when adding a category through the 'Add new post' screen.
Has anyone else seen this problem? Spent the last hour or so trawling the web but can't find anything. I have other blogs running the same version and it doesn't have the problem and there aren't any noticeable differences in set up!
Thanks in advance
