Favorites/Internet Shortcut importing 'bug'
Date: December 19, 2000 08:40AM
some people have reported that not all Favorites are 'imported' by K-Meleon... this is because the implimentation is case-sensitive, i.e. Internet Shortcuts with all-caps extensions ('.URL', as opposed to '.url') are not shown...
