i'm running 3.0.7 and it does not appear to work for the WYSIWYG editor.
basic editor, standard editor (guided or advanced) both work.
i've verified that in WYSIWYG mode that the script does two things:
a) points to:
Code:
<input type="button" value="Spell Check" onClick="spellCheck( 'vbform', 'WYSIWYG_HTML', '2');">
b) that the text area in WYSIWYG is identified correctly, namely it's:
Code:
<input type="hidden" name="WYSIWYG_HTML" id="html_hidden_field" value="<p></p>" />
i was hoping that the js didn't match up to the input name.. but not that easy of a fix!!
