TightVNC dropping port digits in Server and connection fails

[J. E. <epp...@gm...>]

Hello,
I just started using TightVNC and I have found that when I bring up the 
server and input the IP with port# that it drops the first two digits of 
the port and the connection fails. I am using M$ Vista   
(9&%Grrrrrrr&^^&((&^!!!!)
Any suggestions?
Thanks
