I installed Vista on my computer and had no problems with having to disable the firewall, but I am having some problems on my girlfriends computer. I go into Control Panel and then to Windows Firewall. When the Firewall screen is up, I click on Change Settings over to the right and it wont do anything. It wont bring up the screen giving me the option to disable it or anything. Nothing whatsoever happens. I cannot figure out how to disable her firewall if I cant get in to change the settings. If anyone knows I can get around this, I'd appreciate it.
