I configure this module to use inclusions for textareas instead of exclusions. I find this to be more suitable. So when I add a new content type, I go into my profile visibility settings and add in the specific syntax for each textarea for adding and editing.
For whatever reason, you have to use hyphens for the textarea for a nodetype when ADDING a new node, but when editing, an underscore is used.
Is there a specific reason for this? I don't have time at the moment to look thru the code to investigate, but it seems that either underscores or hypens should be used, not both.
