有关ASP.Net的win7中的错误将文件下载到客户端浏览器？

点击第一个链接弹出另存为对话框，然后单击cancel.Next，

点击第二个链接弹出另存为对话框，然后单击cancel.Next，

单击第三连杆弹出另存为对话框，然后单击取消。

目前，在弹出的对话框不显示和网页一样忙于！

条件只是在win7中。在XP中没有问题。

对不起，我的英语不好！的Index.aspx：

其更好地使用下载文件的处理程序，反正在ASPX禁用该页面的会话，然后再试一次。 – Aristos

@ Aristos-感谢您的帮助，您是对的！禁用会话。工作就像一个魅力。你是我的明星 – user1662936
