Adobe’s latest applications allow for multiple user configurations when installed on Windows XP and Mac® OS X. This allows individual users to install and manage their own sets of extensions, and maintain individual system configurations. The Extension Manager allows the current user of the system to view only the extensions installed in the current user’s account. In addition, Dreamweaver allows an administrator to install and manage extensions for all users of a system. To accomplish this, the person must be logged in as Administrator on Windows XP, and as “root” on Mac OS X.
