I just got off the phone with a developer and he tells me you must install the second disk or face serious feature failures. Turns out I had installed 6c115 without installing the second disk, and sure enough, features like: 1. Connect to server would not show me anything deeper than the root directory when connecting to a password based FTP server I have access to. 2. Launch an application would not bring the application to the foreground unless I launched, waited for it to finish loading and then double clicked it/ command-tab to it, or clicked it on the dock. If an application in the foreground had windows open it would obscure the recently launched application until you manually switched to it after the application finished launching. So it appears the second disk is more than print drivers.
