[perl-win32-gui] Address not available

[Gary Kuznitz]

Hi,

I'm getting an error when I run it.
    Address not available. at line -> bind(S, $this) || die $!;

I don't understand why.  Maybe someone could shed some light on it for me.  
I am not familiar with writing perl. If anything else looks weard, I welcome any 
and all comments.  I could send this as an attachment if it doesn't email ok 
but I didn't know if this list accepts attachments.

Thank you very much.
