TYPO3 Core

What are the id's and class names of the div elements corresponding to the tabs containing the editing area?

I checked it again.
The error only occurs in Firefox and Netscape 8 in Mozialla Mode.
With the IE Engine it works ok (Both IE and Netscape).

This is the table initialising the tabs:

<div class="typo3-dyntabmenu-tabs">
  <table cellpadding="0" cellspacing="0" border="0" class="typo3-dyntabmenu">
    <tr>
      <td class="tab" id="DTM-ec62fcaeb7-1-MENU" nowrap="nowrap">
        TAB1
      </td>
      <td class="tab" id="DTM-ec62fcaeb7-2-MENU" nowrap="nowrap">
        TAB2
      </td>
      <td class="tab" id="DTM-ec62fcaeb7-3-MENU" nowrap="nowrap">
        TAB3
      </td>
    </tr>
  </table>
</div>

Hope it helps ...
and thanks a lot for your efforts

Yes, it is a Mozilla problem, of course, this is documented here: http://typo3.org/documentation/document-library/rtehtmlarea/Known_problems-4afe05f34e/#oodoc_part_8972

Any other containing div gets a display: none style property?

<quote>The htmlArea RTE has been modified to support this feature in Mozilla 1.4+ and Firefox 0.8+. The modification does not work in Mozilla 1.3.1.</quote>
But mine is a Mozilla 1.7.8 and Firefox 1.0.4 and it doesn't work correctly.

Any other containing element, besides DTM-ec62fcaeb7-1-DIV, gets a display: none style property?

Please report any JavaScript error that may show up on the JavaScript console.

Please try verison 0.5.5 of htmlArea.

If the problem is not solved, please give me a pointer to a published TYPO3 extension that has the RTE in a hidden tab on initial display.

This problem is resolved in version 0.5.8.
