pop-up window size irregularity

hey all,
i'm not a newbie at all to webdesign, but i've never seen this before and am at a loss. hopefully someone has a tip for me. =) basically, i'm having an issue with calling a pop-up window from flash. it works perfect on the mac (IE) but when viewed on the PC (IE) the window has an additional 150 pixels or so added to it's vertical height.

this is the code i have on my button:
on (release) {
getURL("javascript:openPop('juke.html','juke',220, 29)") ;
}



and this is the javascript code that i put in the flash html page:
function openPop(url,name,popW,popH) {
version = navigator.appVersion;
var w = 800, h = 600;

if (document.all || document.layers) {
w = screen.availWidth;
h = screen.availHeight;
}
var leftPos = (w-popW)/2, topPos = (h-popH)/2;
window.open(url,name,'width=' + popW + ',height=' + popH + ',scrollbars=no,toolbar=no,status=no,resizable=no, top=' + topPos + ',left=' + leftPos);void(0);
}


this is the URL to see what happens:

Any thoughts would be really appreciated!
thanks so much!

The answer is not a good one I am afraid! IE on the PC has a minimum window size, off the top of my head I think it is 50 x 50 px.

Unfortunately I don't know a way round this either.

thanks - yes, someone else said it's something like 100x100 for security reasons or something odd like that. ugh! i guess i have a bit of redesigning to do. thanks for the reply!
