Found the problem... actually a bug!
The javascript at work in manager/frames/tree.php is looking for a <div> in the node code - placed there by nodes.php
End of line 167 in nodes.php (v1.01)
End of line 169 in nodes.php(v1.0.2)
.$pagetitleDisplay.$weblinkDisplay.'</span> '.$pageIdDisplay.'</div>';
Replace with
.$pagetitleDisplay.$weblinkDisplay.'</span> '.$pageIdDisplay.'<div style="display:none;"></div></div>';
(You’re adding
<div style="display:none;"></div>)
At the Moment it’s a ’core hack’ but it does the trick.
Credit to ’kosh_003’ for the mad skills.
