Edit buttons unavailable in Dreamweaver for existing menu
In Dreamweaver design view, when I select an existing Webassist menu, the properties panel makes available the button for "Edit menu" but the buttons for "Edit Content" and "Edit Theme" are grayed out. Additionally, if I select "Edit menu," I am only given the opportunity to create a new menu. The existing menu is not available in the drop down lists.
The menu is operating properly on the web page and I can see its files in the CSSMenuWriter directory in a sub-directory called cssmw1, containing menu.css, menu.js and menu.php files.
The only thing I've done that may be a little unorthodox was to edit menu.css with a path to hover images in my default images directory instead of in the cssm1_images directory.
I would greatly appreciate any advice. While I can edit the menu files by hand, it's nice to have the graphical interface in Dreamweaver and would prefer to get that working again.
