Starting a RDP session with personal credentials

If I set up a RDP session entry to use my personal credentials as default, it logs me right into the RDP system no problem. Also if I need to "Reconnect", I have no issues. However, if other credentials are configured on the entry by default, and I right-click on the RDP entry to start a new session and I go to the "Open with parameters" menu and select "Open (Select Credential Entry)..." then I chose "Use My Personal Credentials", it loads the username properly but it still prompts me for a password. Is this a limitation of Windows, is this by design in RDM or possibly a glitch? Also, when opening the RDP session with different credentials, if I need to "Reconnect" to the session, it prompts me for my password to reconnect. I assume that prompting for my password to reconnect is for the same reason that it prompts me for a password to initially establish the session?




Thanks
