急：window.open()方法为什么开始能弹出对话框，多次之后就无法弹出对话框？

Question

是不是资源没有回收
NetScape仍然认为小窗口已经打开?
我的想法，有点无稽。

guihengzhang:我也考虑过这种可能，但每次弹出都会更新dialogWin.win，不应该呀
woyingjie :窗口名是用toDay.getTime(); 设定的，应该不会重名我将代码整理一下：
function openDialog(url, width, height, returnFunc, args) {
    if (!dialogWin.win || (dialogWin.win && dialogWin.win.closed)) {
// Initialize properties of the modal dialog object.
dialogWin.returnFunc = returnFunc
dialogWin.returnedValue = ""
dialogWin.args = args
dialogWin.url = url
dialogWin.width = width
dialogWin.height = height // Keep name unique so Navigator doesn't overwrite an existing dialog.
var toDay = new Date();
dialogWin.name = toDay.getTime(); 
// Assemble window attributes and try to center the dialog.
if (Nav4) {
    dialogWin.left = window.screenX + 
   ((window.outerWidth - dialogWin.width) / 2)
    dialogWin.top = window.screenY + 
   ((window.outerHeight - dialogWin.height) / 2)
    var attr = "modal,dialog,screenX="  + dialogWin.left 
                        + ",screenY=" + dialogWin.top 
                        + ",resizable=no,width=" + dialogWin.width 
                        + ",height=" + dialogWin.height
} else {
    dialogWin.left = (screen.width - dialogWin.width) / 2
    dialogWin.top = (screen.height - dialogWin.height) / 2
    var attr = "modal,dialog,left=" + dialogWin.left 
                       + ",top=" + dialogWin.top 
                       + ",resizable=no,width=" + dialogWin.width 
                       + ",height=" + dialogWin.height
}

globalAttr = attr;
alert("in openDialog attr = " + globalAttr 
+ "\ndialogWin.url = " + dialogWin.url 
                  + "\nurl = " + url 
+ "\ndialogWin.name = " + dialogWin.name);
dialogWin.win=window.open(dialogWin.url, dialogWin.name, attr)
//if (dialogWin.win == null) {
alert("dialogWin.win = " + window.open);
//}
dialogWin.win.focus()
    } else {
        dialogWin.win.focus()
    }
    return dialogWin.win;
}

测试了一天，发现运行到调用window.open时，画面没有加载，方法一直没有返回，其他的NetScape窗口上无法操作。高手们帮帮忙啊！！
