Where is this fork you keep mentioning?
Holy cripes... I posted the wrong source! How did I manage that?
The call to &startup was replaced in a later version with 
    defined(my $pid = fork) or die "Cannot fork: $!";
    unless ($pid) {
           # Child process is here
           system ('maincnc.exe');
    }
    # Parent process is here

Problem is fixed now, using exit;after the system(). I must have accidentally opened the older version of the script after rebooting my computer, rather than the new version. Maybe I'd have had beter help if I posted the correct source!
You guys were great in helping me anyway. Thanks for all the feedback!
