PowerMessanger and CSSMenuWriter
If you have a pre built website that already contains a CSSMenuWriter menu in it, I have found that when you run the "Add Content to PowerCMS" for the first time it over writes your menu files. This must be a bug. I overcame it by renaming my CSSMenuWriter/cssmw folder to CSSMenuWriter/cssmw0 BEFORE I ran the "Add Content to PowerCMS" wizard.
