Currently have a site in final stages of dev on WP 3.4.1. I'm planning to upgrade to WP 3.5.1. Read everything I can find on attempts to run multisite in localhost environment. Not pretty. I'm looking for feedback on downloading WP 3.5.1 to a new/separate folder for dev of 2nd site. I'm not using any DBs. Are there hardcoded references in WP that will create havoc running WP out of 2 folders? For example, .../wordpress and .../wordpress2? Particulars: Windows 7, WebMatrix 2.
