I had installed the CSS Flyout mod for 1.3 - I have since decided to uninstall it - so I removed all the files thta I had uploaded.

Unfortunately I can't find something that is triggering it in the Admin. If I go to Tools -> Layout boxes controller, it does correctly recognize the fact that sideboxes/categories_css.php is missing, but how to I get it to realize that the whole module is gone?

Does it matter? (Other than it's aesthetically displeasing to me every time I go to tweak my sidebox layouts ;) )

TIA!
