i tried to follow your instructions for windows users, but there is a problem:
in the folder "preferences" there are two files: the first is "com.apple.Safari.plist" and the second is "PubSub.plist", even if I think that the second one is useless for our target. I opened and modified the first one because the name was the same of the command in the Apple users' instructions, but it doesn't work... besides when I open the xml file in the notepad there's a little thing like a square font before and after every single "key" in the file, so I copied and pasted at the end of the key that you gave.. but it doesn't work....so what could we do?
PS: I'm sorry for my english, but I'm italian and I'm not so good...:) I hope you will understand what I wrote.
