I've been playing around trying to make my own web site and I've run into the same problem. I am having trouble saving the document the right way. I am using Panther and typing my html in TextWrangler. When I go to save it I am titling it "mypage.html" and then it saves as a word file. I open my browser and click on open file and select my file, and instead of an html file it displays as, file:///Users/name/Desktop/untitled%20folder/mypage.html. How can I fix this?
