Projectmanager description

Hi,

we updated to 1.2.105. However, previously reported bug for projectmanager description tab textarea not visible is not fixed (using Internet Explorer 6.0). I tried to find it, but am not a programmer and am not able to fix it.
Below I show the html source for the description part and also the part of the file:
/egroupware/projectmanager/setup/etemplates.inc.php

I think somewhere in bold text is the problem, please help to fix this bug.

file:
$templ_data[] = array(‘name’ => ‘projectmanager.edit.description’,
‘template’ => ‘’,
‘lang’ => ‘’,
‘group’ => ‘0’,
‘version’ => ‘0.4.001’,
‘data’ =>
‘a:1:{i:0;a:6:{s:4:“type”;s:4:“grid”;s:4:“data”;a:2:{i:0;a:1:{s:2:“c1”;s:4:",top";}i:1;a:1:{s:1:“A”;a:3:{s:4:“type”;s:8:“htmlarea”;s:4:“name”;s:14:“pm_description”;s:4:“size”;s:107:“width: 100%; height:100%;,TableOperations,ContextMenu,ColorChooser,FontChooser,SearchReplace,InsertDateTime”;}}}s:4:“rows”;i:1;s:4:“cols”;i:1;s:4:“size”;s:8:“100%,260”;s:7:“options”;a:2:{i:0;s:4:“100%”;i:1;s:3:“260”;}}}’,
‘size’ => ‘100%,260’,
‘style’ => ‘’,
‘modified’ => ‘1112698666’,);

html source:

       <textarea id="exec[pm_description]" name="exec[pm_description]" style="width:100%; height:100%;">
                     </textarea>           </td>

Kind regards Wilfred
