How I did What

It is simply possible with Editor - CodeMirror available as one of the default plugin. To make it available, you have to unpublish Editor - TinyMCE. So go to Extensions in the admin panel, drop down to Plug-in Manager. Just disable  Editor - TinyMCE. Then go to your content and insert any <iframe> .... </iframe> code. Once you disable TinyMCE, CodeMirror becomes active. If you want to revert to TinyMCE, just enable it after saving your article article.  If found useful, buy me coffee for the time you saved.

Problem lies in index.php of beez3 at line no 159 <?php if ($showRightColumn) : ?> <div id="close"> <a href="#" onclick="auf('right')"> <span id="bild"> <?php echo JText::_('TPL_BEEZ3_TEXTRIGHTCLOSE'); ?> </span> </a> </div> So just get rid off the following lines of code                      <div id="close"> <a href="#" onclick="auf('right')"> <span id="bild"> <?php echo JText::_('TPL_BEEZ3_TEXTRIGHTCLOSE'); ?> </span> </a> </div> 

What to do  Just remove preferences file. File name is XPress Preferences.prf Where is the file located? C/Documents and Settnigs/User (may be your name)/Application Data/Quark/QuarkXPress 6.0/XPress Preferences.prf Once the file is deleted, shut down the computer, restart, open QuarkXpress. The system will create XPress Preferences.prf by itself. More Info If you are using older versions of Quark, look for the Preferences folder in C/Programme Files/Quark/QuarkXPress Location of file / folder may very in different operating systems.  If found useful, buy me coffee for the time you saved.
