Okay, I have installed LW 2.7.13. I have tuned off Zonealarm. I then went to another PC in my house and tried to access a file that was on my other PC. I found that file, and my IP address was shown in black, indicating no firewall problems. But when I highlighted my IP address, and clicked to download it, it immediately went into the Requerey mode. And I had no other uploads going on that PC. So why can't I access my PC ( i.e. share files with others) when everything looks good?
