In the preview area, I only see this text image : Click Here to Open preview. If I click on this text, I have the user/Library/Application%20Support/Adobe/Dreamweaver%209/Configuration/WAPreview/wamw.html to be open with this text into the page : -32 style="overflow: hidden;"
If I apply the menu to a page, I have no problem with it. It's Ok and view it. It's only the preview that I can't see into CssMenuWriter.
