You could try the following:

In your index.phtml (after you initialize oApp) put:

if( isset( $_POST['childWin'] ) && strlen( $_POST['childWin'] ) > 0 )
     $oApp->setVar( 'childWin', strtolower( $_POST['childWin'] ) );

In your template form put:

<input type="hidden" name="childWin" value="[$szChildWin|NULL$]">

In your javascript function include (forms[0] assumes you only have one 
form in the template):

if( document.forms[0].childWin.value != "NULL" )
     // the window has been opened prior to submit so get a handle on it
     // reference it by name
     //open the window
     wh = window.open.......
     // set the hidden var
     document.forms[0].childWin.value = wh;


You'll have to update your TemplateParser.php script from cvs for the 
preprocessing to work properly.

This is untested code ;)
