Column resize bug with Firefox 1.0.5

Behavior of dispatchEvent method had changed in Firefox 1.0.5 causing JS exception and column resize problems in the grid control:

Error: [Exception... "Component returned failure code: 0x80070057
(NS_ERROR_ILLEGAL_VALUE) [nsIDOMEventTarget.dispatchEvent]"
nsresult: "0x80070057 (NS_ERROR_ILLEGAL_VALUE)"  location: "JS
frame :: .../runtime/lib/browsers/gecko.js :: anonymous :: line ..."  data: no]
Source File: .../runtime/lib/browsers/gecko.js Line: ...

Add the following code to your scripts to fix the problem:

if (window.HTMLElement) {

    var element = HTMLElement.prototype;

    var capture = ["click", "mousedown", "mouseup", "mousemove", "mouseover", "mouseout" ];

    element.setCapture = function(){
        var self = this;
        var flag = false;
        this._capture = function(e){
            if (flag) {return}
            flag = true;
            var event = document.createEvent("MouseEvents");
            event.initMouseEvent(e.type,
                e.bubbles, e.cancelable, e.view, e.detail,
                e.screenX, e.screenY, e.clientX, e.clientY,
                e.ctrlKey, e.altKey, e.shiftKey, e.metaKey,
                e.button, e.relatedTarget);
            self.dispatchEvent(event);
            flag = false;
        };
        for (var i=0; i<capture.length; i++) {
            window.addEventListener(capture[i], this._capture, true);
        }
    };

    element.releaseCapture = function(){
        for (var i=0; i<capture.length; i++) {
            window.removeEventListener(capture[i], this._capture, true);
        }
        this._capture = null;
    };

}
