I am using windows Vista on a pc with Dreamweaver cs 5.5
Here is an example of code not working with the new editor.
But the code is working in the browser on the Internet?

<tr valign="baseline">
        <td nowrap align="right">Product Directory</td>
        <td colspan="2"><label for="StoreProductDir"></label>
          <textarea id="StoreProductDir" name="StoreProductDir" class="dmxEditor office" style="width:728px;height:300px"><?php echo $row_Store['Store_Product_Directory']; ?></textarea>
<script type="text/javascript">
  // <![CDATA[
 jQuery(document).ready(
   function()
     {
       jQuery("#StoreProductDir").dmxEditor(
         {"FileManager": {"path": "../../images/store-images/products/ProductPage2/ProductDir", "subFolder": "ProductDir", "view": "thumb", "showThumbs": true, "allowUpload": true, "allowDelete": true}, "ImageGallery": {"path": "../../images/store-images/products/ProductPage2/", "subFolder": "ProductDir", "allowUpload": true, "allowDelete": true}, "width": 728, "noScript": false, "allowUpload": true, "uploadPath": "../../images/store-images/products/ProductPage2/ProductDir", "subFolder": "ProductDir", "uploadProcessor": "php", "allowResize": true, "resizeMaxWidth": 98, "resizeMaxHeight": 200, "iconSet": "colorful_32", "includeCss": "../../buddystyle7cp.css", "skin": "office", "formatterSettings": {"linkType": "full"}, "toolbars": {"Text": {"items": {"subscript": false, "superscript": false, "indent": false, "outdent": false}}, "Insert": {"items": {"inserthorizontalrule": false}}, "Search": {"enabled": false}, "Code": {"enabled": false}}, "extensions": ["FileManager", "ImageGallery"]}
       );
     }
 );
  // ]]>
</script>
          [br]
        [br]</td>
      </tr>

Advanced HTML Editor 3.3.1 is working with some of the old editor script I am using windows Vista on a pc with Dreamweaver cs 5.5

code not working with the new editor But the code is working in the browser on the Internet?

The code in Dreamweaver should show the editor in the property window at the bottom of dreamweaver but it does not show when you click on the form that has the editor.
Some of the older code from the HTML editor 3.0 shows the editor in the property window at the bottom of Dreamweaver.
The problem is in Dreamweaver.
When I click on the code that does not show the editor and then go to a different page the editor in the property window does not show I have to close Dreamweaver and restart Dreamweaver to have the editor work so I can edit the form.

I just copied and pasted the code you provided and the editor shows just fine in the properties inspector.
Please uninstall the extension, clear your DW cache: www.dmxzone.com/go?16740 and restart DW. Then install the extension again.

The clearing of the cash helped, But I it still has problems with some of the editors.
Problem:
I open the file and go to the form textarea and no editor button bar and when I click on the textarea the editor does not show in the properties inspector.
When I click on the HTML Editor buton on the top of Dreamweaver I get this error:
Whil execution onLoad in dmxAdvHTMLEdit3.htm, the folowing javaScript error(s) occurred:
At line 563 of file "C:/users\Foster\AppData\Roaming\Adobe\Dreamweaver CS5.5\en_US\Configuration\Shared\DMXZone\Advanced HTML Editor3\dmxAdvHTMLEditor3_lib.js:
The Toolbar has no properties

It is somthing with this code that the HTML Editor 3.3.1
has a problem with.

<script type="text/javascript">
// <![CDATA[
jQuery(document).ready(
function()
{
jQuery("#pageadded".dmxEditor(
{"ImageGallery": {"path": "../images", "subFolder": "pages", "allowUpload": true, "allowDelete": true}, "FileManager": {"path": "../images", "subFolder": "pages", "showThumbs": true, "allowUpload": true, "allowCreate": true, "allowRename": true, "allowDelete": true}, "width": 550, "height": 800, "noScript": false, "lineBreak": "p", "allowUpload": true, "uploadPath": "../images", "subFolder": "pages", "uploadProcessor": "php", "iconSet": "colorful_32", "includeCss": "../buddystyle7cp.css", "locale": "en", "formatterSettings": {"linkType": "full"}, "toolbars": {"Text": {"items": {"subscript": false, "superscript": false, "indent": false, "outdent": false}}, "Lists": {"enabled": false}, "Table": {"items": {"insertRowAfter": false}}, "Insert": {"items": {"deletelink": false, "insertspecialchar": false}}, "Code": {"enabled": false}}, "extensions": ["FileManager", "ImageGallery"], "toolbarsOrder": ["Text", "Format", "Lists", "Table", "Insert", "Font", "Style", "History", "Common", "Code"]}
);
}
);
// ]]>
</script>

The problem seems to be in the tool bar.
If I take out the tool bar code it works.
Example:
Code before:
This is the old Editor Code that does not work
"toolbarsOrder": ["Text", "Format", "Lists", "Table", "Insert", "Font", "Style", "History", "Common", "Code"]

Changed code for tool bar:
This works:
"toolbars": {"History": {"enabled": false}, "Text": {"items": {"subscript": false, "superscript": false, "indent": false, "outdent": false}}, "Format": {"enabled": false}, "Table": {"enabled": false}, "Insert": {"items": {"inserthorizontalrule": false, "insertspecialchar": false}}, "Search": {"enabled": false}}

I have found the problem:

What to do:
Take out this code save page and restart Dreamweaver
That will make your tool bar and program work.

The code to take out:
, "toolbarsOrder": ["Common", "History", "Lists", "Text", "Format", "Table", "Insert", "Search", "Font", "Style", "Code"]

I hope that this helps.
