yah that's a header.tpl thing

Code
<a title="{$lang.CHANGE_MOOD}" style="text-decoration: none" href="javascript: void(0);" onclick="javascript: window.open('{$config.BASE_URL}/ubbthreads.php?ubb=changemood','mood','toolbar=no,directories=no,location=no,scrollbars=yes,menubar=no,width=300,height=200')">

that's 7.2.2 stock right now.

that 300px kinda gets in the way, espcially when you have a wapper vying for realestate..

i know i change mine to something different, and it worked. i believe it was two-fold though.

1. change header to have a more flexible chromeless popup
2. change the template of the filemanager as well, to remove the wrapper as well as to go with % on the widths..
