IE hangs up when writing Javascript to window

I have some javascript code that is called by some HTML on our server (no problem when running locally). The following
is the scenario and code. I would appreciate any help I can get to solve this problem. The problem does not occur when using Netscape or Mozilla. Are there some type of buffer limits in IE, and how od I get around them?

Note, when I put in an "alert" statement in my JS code in the middle of the document (marked by ************
for clarity) creation the problem "goes away" in IE. I try to intermittently open and close the document to try and break the buffer, but it does not help.

Any help would be appreeciated.

Thanks...Larry

1. Opening a new window, using the method window.open
2. The following is a code bit:

test = window.open('','ASSESSMENT',
'toolbar=no,width=640,height=480,status=no,scrollbars=yes,resizable=yes,menubar=no');
//window.focus();

with (test.document)
{
open();
write('<html>\n<head>\n' + '<title>GoToLearn ' + formID + ' Assessment</title>\n');
