Popups and Privatemsg

I have a porblem with popups. Sorry for my bad English, I hope they understand what I want.

/ **
* Integration of hook_popups () of the popups module.
* /
privatemsg_popups function () (
if (variable_get ( 'privatemsg_popups', TRUE)) (
return array (
'*' => Array (
'a [href *= messages / new'] / / Write new message
)
'*' => Array (
'div # block-menu-privatemsg-privatemsg a [href *= messages / new]',
)
);
)
)

When I activate the block on messages it goes with popups, but this only because I want somewhere to activate the road is probably 'a [href *= messages / new]' wrong so I need to change it.

Popups should be applied for 1 + 2 to 3 works. Here the link of the messages / new is correct.
When 1 + 2 is the link messages/new/1 / and messages/new/6 *** / ***
How can I change the path in the modules, the popups will work on 1 +2. Regards
