CPF turned off when using fastuser switching of XP

Hope this is the right place to post this question.

I don’t exactly know how to describe it but I will try to make it simple.

I am testing a software called Winconnect server. It supposed to turn a XP Pro into a terminal server. The problem here is, the first user that connect gets the CPF2.4 with all status green, however, the second or subsequent users get the CPF2.4 with all status red. (See attached, first session was thru RDP, 2nd was thru VNC, the status color are clearly visible). The question here is, the user session with CPF status all in RED, is he/his session protected at all? In fact, CPF will prompt an error message that a session of the CPF is already running. If the second session (and so other) is not protected, how do I overcome this problem?

Thanks in advance for any valueable advice.
