Need scrollbars in EI7 / pop up interval timing off

I’m working on a kiosk project for IE7 that has several different types of pop-up’s that must stay a fixed size.

The first problem is that IE will NOT show the scrollbars that are needed to review the full pop-up.

Here’s and example of a line:
<script type="text/javascript">
function openWinMenuUrl()
{
NewWindow=window.open
('http://www.aol.com', 'menu_url',
'width=1000,height=600,location=yes,menubar=no,resizable=no,scrolling=yes');
}
</script>

The second problem is that my pop-up timer (respectfully snagged from javascript kit) will not pop-up at the timed interval –only onload, and when you click either of the 2 buttons in the pop-up it performs no action.

<script type="text/javascript">
//JK Popup Window Script (version 3.0)- By JavaScript Kit (http://www.javascriptkit.com)
//Visit JavaScriptKit.com for free JavaScripts
//This notice must stay intact for legal use
//Win Type: Pop Up | 5 minutes period

//Specify URLs to randomly select from and popup/popunder:
//To display a single URL, just remove all but the first entry below:
var popurls=new Array()
popurls[0]="return3.html"

function openpopup(popurl){
var winpops=window.open(popurl,"","width=290,height=200")
}
function get_cookie(Name) {
var search = Name + "="
var returnvalue = "";
if (document.cookie.length > 0) {
offset = document.cookie.indexOf(search)
if (offset != -1) { // if cookie exists
offset += search.length
// set index of beginning of value
end = document.cookie.indexOf(";", offset);
// set index of end of cookie value
if (end == -1)
end = document.cookie.length;
returnvalue=unescape(document.cookie.substring(offset, end))
}
}
return returnvalue;
}
popfrequency="5 minutes"
function resetcookie(){
var expireDate = new Date()
expireDate.setMinutes(expireDate.getMinutes()-10)
document.cookie = "jkpopunder=;path=/;expires=" + expireDate.toGMTString()
}
function loadornot(){
if (get_cookie('jkpopunder')==''){
openpopup(popurls[Math.floor(Math.random()*(popurls.length))])
var expireDate = new Date()
expireDate.setMinutes(expireDate.getMinutes()+parseInt(popfrequency))
document.cookie = "jkpopunder="+parseInt(popfrequency)+";path=/;expires=" + expireDate.toGMTString()
}
}
if (get_cookie('jkpopunder')!=parseInt(popfrequency))
resetcookie()
loadornot()
</script>

As a side note, the whole project works in Safari, except I get the same onload issue with the timer.

Any ideas or alternative suggestions are appreciated. Thanks!
