nope I do not have this issue with this one and nor  did I have it with the example. But when I integrated the editor into  the application using the 'include', than the issue apppeared.

1) in the IE, the textare white box displays although the text area is not expended; the preview and the and the HTML are not the same size as the 'original"

2) in Firefox, the textarea displays the same (not expended) however, there is no 'white' area for the text; the preview and the HTML are not the same size either.
