Re: hthought - WinXP can create blank folders by using copy/paste during a rename using particular unicode characters; Windows won't paste the character.. but instead renames the folder as having no name.
I've done tests, and these folders work fine on all Linux, Mac, and Windows... oddly enough
And.. re: venegal - This is for a homebrew plug-n-play CMS (you just drop it on a PHP5 server and run it... and it works.) - So no htaccess is "allowed" for this one
That being said - Any suggestions?
