Code (markup):

I have included the php file below

If i change the position from relative to fixed, IE6 displays correctly but firefox and IE7 wont.

 

Here is the open.php file that i am specifically having the issue with.

<?php
$title=($cfg && is_object($cfg))?$cfg->getTitle():'osTicket :: Support Ticket System';

?>

I have resolved the issue.

In main.css I made the following changes.

Change

body {
  font-family:arial, helvetica, sans-serif;
  font-size:9pt;
  margin:0;
  padding:0;
}

* { position:relative; }

Code (markup):

to

body {
  font-family:arial, helvetica, sans-serif;
  font-size:9pt;
  margin:0;
  padding:0;
  text-align:center;
}

/* * { position:relative; } [comment out or delete]*/change

Code (markup):

and

#container {
  width:760px;
  margin:5px auto 0 auto;
  border:1px solid;
}

Code (markup):

to

#container {
  width:760px;
  margin:5px auto 0 auto;
  border:1px solid;
  text-align:left;
}
