if you downloaded the package with php3 you havent changed updated your style to reflect this.
HTML Code:
[<a href="#" onclick="open_smilie_window(smiliewindow_x, smiliewindow_y, $wysiwyg); return false" title="<phrase 1="$vboptions[smtotal]" 2="$totalsmilies">$vbphrase[showing_x_smilies_of_y_total]</phrase>">$vbphrase[more]</a>]
Thats the code to call the popup box.
