I just bought the CS5 and installed the DHTML extension but it will not work -
it will not work in opening existing menus nor in starting a new menu in a
new project - IT KEEPS TELLING ME THAT MY PROJECT IS NOT OPENED -
it is obviously opened because a previously made menu already is there
how can I get this extension to open and create menus like it is supposed to in CS5?
You say that you installed "the DHTML extension". A search of the Dreamweaver exchange for "DHTML" yeilds 33 results.
What specific extension did you install? Have you tried to contact the developer?
Sometimes help info is available listed in the Extension Manager when you select the extension.
