Error- Multiple popups crashes IE while trying to pass value between two windows

Hi friends,

I've lost almost half a day to identify/recover this script error.I often got this type of error.

I've parent window with two text field.There user can either enter the value on the field or choose popup option to search & select the value.When user open the popup & selects value, the selected value gets populated to parent window text field & close popup window. Everything working well, but sometimes after closing popup window, it keeps on opening same popup window multiple time until my internet explorer get crashed. It happens only in IE.

Here is the snippet of parent window:

Code:

<SCRIPT language="Javascript">
function winpop(stringURL) {
	var pop_window = window.open (stringURL, 'popWin', 'scrollbars=yes,status=yes,top=10,width=750,height=650,location=no,menubars=no,toolbars=no,resizable=no');
	if (window.focus) {pop_window.focus()}
	return void(0);
}
</SCRIPT>

<body>

<form name="GetClntAcctForm" method="post" action="/JFactors/FAGetClntAcct.do?do=get" onsubmit="return validateGetClntAcctForm(this);">
	
	<input type="hidden" name="tranType" value="">
	<input type="hidden" name="showFactor" value="N">
	<input type="hidden" name="programId" value="">
    <table class="tablestyle1" border="0" cellpadding="3" cellspacing="1" width="100%">
        <tbody>        
            <tr>
				<td class="labelstyle1">Client Account </td>
				<td class="inputstyle1">
					<input type="text" name="clnt" maxlength="10" size="15" value="" style="text-transform: uppercase">&nbsp;
					<input type="text" name="acct" maxlength="6" size="15" value="" style="text-transform: uppercase">&nbsp;
					<a  href="javascript:winpopup('popup.html?parent=GetClntAcct&search='+document.forms[0].clnt.value+'&type=8&acct='+document.forms[0].acct.value);">
						<img src="/JFactors/images/search.gif" height="18" width="18" border="0" alt="Search"></a>	
						<input type="submit" value="Go" class="btnstyle1">
				</td>            	
            </tr>
        </tbody>
    </table><br/>
	
</form>
</body>

Here is the snippet of popup.html

Code:

<SCRIPT language="Javascript">

function closepop(parentName, stringParam) {
	 if ((parentName == "GetClntAcct")) {
	     window.opener.document.GetClntAcctForm.clnt.value = stringParam.substring(0, stringParam.indexOf(";clntacct;"));
   	     window.opener.document.GetClntAcctForm.acct.value = stringParam.substring(stringParam.indexOf(";clntacct;")+10, stringParam.indexOf(";clntname;"));
		 
	window.opener.focus();
	window.close();

}
</SCRIPT>

<body>
		<fieldset/>
				
		<form name="ClientAcctForm" method="post" action="/JFactors/FAClientList.do">
		<h1>select a Client:</h1>
		<BR>
		<table class="tablestyle1" border="0" cellpadding="3" cellspacing="1" width="100%">

		                  </tr>
		            	
				        
						<tr class="disprecstyle1 ">
							
        					<td>      
        						<a href="#" onclick="javascript:self.close();">AZU397&nbsp;D1NSGD</a>              	                	      	                	    	                    	
		                    </td><td>AZU397     Long Name</td>		        
		                  </tr>
		       </tbody>
		</table>
		</form>
</body>

Need to first track down what code is *DOING* the multiple opens.

You might put an alert( ) just in front of any window.open you are doing, so you can see if you are getting unexpected calls to that particular window.open.
