Pressing "enter" in ExtJS-generated search box not working in IE
I inherited some code and I'm trying to isolate a bug that we found in IE only. ExtJS is used to generate a searchbox. Ext creates an `<img>` that acts as the trigger for searching. 

In IE, you can click on the img to submit the search. However, if you press enter it activites an onClick button that appears farther down the page. Code below. How can I make sure the 'specialkey' is assigned to trigger the search? (I'm a little unclear why it works ok in non-IE browsers).

    Ext.onReady(function(){
    // create user extensions namespace (Ext.ux.form)
    Ext.namespace('Ext.ux.form');
    
    //  Ext.ux.form.SearchableTextField constructor
    Ext.ux.form.SearchableTextField = function(config) {
        // call parent constructor
        Ext.ux.form.SearchableTextField.superclass.constructor.call(this, config);
        // associate ENTER key with button click
        this.on('specialkey', function(f, e) {
            if (e.getKey() == e.ENTER) {
                this.onTriggerClick();
            }
        }, this);
    } // end of Ext.ux.form.SearchableTextField constructor
    
    // extend
    Ext.extend(Ext.ux.form.SearchableTextField, Ext.form.TriggerField, {
        triggerClass: 'x-form-search-trigger',
        onTriggerClick : function() {
            alert('customize in you app code');
        }
    }); // end of extend
	var tb = new Ext.Toolbar({
		renderTo: 'searchbox'
	});

	var search = new Ext.ux.form.SearchableTextField({
		triggerClass:'x-form-search-trigger banner-searchbox-submit',
		id:'banner-searchbox',
		width:100,
		onTriggerClick: function(){
			var x = this.getRawValue();
			this.setRawValue('');
			document.forms[0].method = 'post';
			document.forms[0].action = 'find.php?site=<?=$site?>&lang=<?=$lang?>';
			document.forms[0].qrystring.value = x;
			var pN = document.getElementById("pageNum");
			if (pN != null) {  
				document.forms[0].pageNum.value = 1;
			}
			document.forms[0].submit();
		}
	});
	var searchPat = tb.add('-','<?=$menuPatients[$lang][2]?>: ', ' ', search);
	tb.doLayout();
