I have been looking at this for hours and I can't seem to locate the source.  I am only receiving this error in Internet Explorer, I am receiving "Type Mismatch" at line 86.  However line number is worthless in IE because error handling in IE sucks. 

It declares the following error is in the text.php page and occurs when I click the "process" button.

[code]
<html>
<head>
<script type="text/javascript" src="chat_app.js"></script>
<script type="text/javascript">
var timeron = false; // timer on indicator
var closetimer = null ; // timer to control smilies
var user = "maryj"; // assign user

if(timeron == false)
{
closetimer = setTimeout("hidesmilies()",5000);
timeron = true;
}

timeron = false;
}

}

Okay, after doing some research I have located the issue.  The issue is a AJAX issue, with IE you have to declare NEW function(this.req.handler)) for some odd reason.  Microsoft is just screwy like that I suppose.

PS > For those that were interested here is the code:

[code]
if (navigator.appName=="Microsoft Internet Explorer")
sendReq.onreadystatechange = new Function(handleSendChat(logout));
else
sendReq.onreadystatechange = handleSendChat(logout);
[/code]
