Ok, i've changed the code and now works in 3.6.7 PL1:

<script language="JavaScript">
function pop_window() {

window.open('http://www.domain.xxx/forum/radioandtv.php', 'popup', 'width=700, height=500, top=100, left=100, menubar=0, scrollbars=1, location=0, toolbar=0, resizable=1, status=0');

}
</script>

and

<td class="vbmenu_control">
<a href="" onclick="pop_window(''); return false;">Radio & TV</a></td>

Bye !
