[newbie] netscape mail problem

[Joe Marcom]

Good day, all;
I am trying to transition my system from window$ to Linux. Yet another
problem: when I try to open Netscape messenger and get my mail,
Messenger asks for my password, then shuts down Netscape as soon as I
enter it (back to KDE).Help??  I'm running L-M 6.0 w/Communicator 4.6.
        Regards,
        Joe
