【问题描述】：

我有一个带有叠加层的弹出窗口，它应该防止下面的文本选择。但是在 IE 中，如果我选择弹出文本，覆盖下的文本也会被选中。如何解决？弹出文本应该是可选择的。

Here 是它的样子。

这里是html代码：

<body style="margin: 0;
             padding: 0;
             text-align: center;">
    <div class="topfixed" style="height: 200px;
                                 top: 0px;
                                 left: 0px;
                                 right: 0px;
                                 position: fixed;
                                 z-index: 0;
                                 background-color: red;">
        <div>Header</div>
        <div>Header</div>
    </div>
    <div class="content" style="margin-top: 200px;
                                position: relative;
                                z-index: 1;
                                background-color: blue;">
        <div>Content</div>
        <div>Content</div>
    </div>
    <div class="overlay" style="top: 0px;
                                bottom: 0px;
                                left: 0px;
                                right: 0px;
                                position: fixed;
                                z-index: 10;
