Me and Mark both cant duplicate that issue, so its a guess in the open,
in sources/user_cpl.php find
	
	
	
		PHP:
	
	
		        $TMPL['user_cp_main_menu'] .= '<div id="user_cp_main_menu">';
	 
 and replace it with
	
	
	
		PHP:
	
	
		        $TMPL['user_cp_main_menu'] = '<div id="user_cp_main_menu">';
	 
 This has allready been changed for the 0.3 release
