getURL prevents 'closewindow' script from initiating

I have an HTML page launching a new window that holds a SWF. From the SWF online, after I launch a ZIP download prompt window from getURL code, the FLASH EXIT button that is coded with ‘closewindow’ stops working.

The EXIT button (closewindow) works fine after I launch another HTML window or PDF file.

I am using:

on (press) {
getURL(“pathnamehere/filename.zip”);
}

and:
on (release) {
getURL(javascript:window.close();");
}

and in the HTML page to launch the new window:
<script language=“JavaScript” type=“text/JavaScript”>
<!–
function MM_openBrWindow(theURL,winName,features) { //v2.0
window.open(theURL,winName,features);
}
//–>
</script>

Any takers?

Thanks!
