Question: I made a change to one of my pages. Why don't I see any change when I browse the site?
Answer: Did you save the page before you browsed it? If you don't save the changes to your files, you will not see the changes you made when you load it into a browser.
Question: I double-clicked on my page in the Finder to open it. Why can't I edit it?
Answer: When you double-click on a page, it will open in a browser (probably Safari), not in Netscape Composer. To learn how open the pages in Mozilla Composer, go to the page about opening files to edit in Mozilla.
