This is an intentional design decision. We think it's a better user experience to prompt for login at the start, and after login we cache some information about your server-namespace environment that is used throughout the session. You can get the behavior you want by having separate workspaces for the folders that you don't usually use together. Then when you open one of them you'll only be prompted for the server connection for that one. You can also consider putting the credentials in plain text in the intersystems.servers block. Then you'll never be prompted. This isn't secure though.
