Default setup and blank site, still nothing.
OK, there is definitly a bug here somewhere...
I went through and deleted EVERY instance of any code on my site that had anything to do with the HTMLEditor. The HTMLEditor folder, and all site files that had any refs to the editor in them.
Then I created a new page and used the extension to insert a new editor on the page.
I set up the styles to point to my css file following the getting started guide for the editor to the letter and used the defaults for everything except the styles.
Nothing, no styles, nada, zip. Love that "Red Text" style.
Note: If the HTMLEditor extension can't insert a new editor on a page using the default settings with the only change being styles applied from a css file that i'm using on other pages and that dreamweaver says is formated correctly...
It's kind of broken isn't it?
