server issue (bug?) on W2K

[Frank B. <fb...@sy...>]

TightVNC 1.3.10 installed as service on Win2000 SP4 workstation.

Connection ports changed to 2002 (main) & 2001 (http).

With this setup, we *did* connect to port 5900 and saw the W2K login. 
At first keypress; the server closes connection and refuses any new 
connections on port 5900.

Why did it not refuse the initial connection to port 5900?
