看了个帖子，发现个问题，关于WebBrowser的

[cklvxd]

private void webBrowser1_DocumentCompleted(object sender, System.Windows.Forms.WebBrowserDocumentCompletedEventArgs e)
{
WebBrowser1.Document.MouseDown += new HtmlElementEventHandler(Document_MouseDown);
WebBrowser1.Document.MouseMove += new HtmlElementEventHandler(Document_MouseMove);
WebBrowser1.Document.MouseUp += new HtmlElementEventHandler(Document_MouseUp);
}

private void Document_MouseDown(object sender, HtmlElementEventArgs e)
{
// Insert your code here.
}
点击一下，Document_MouseDown会相应2次；
比如，count++，count每点一次，增加2， 这是为什么？

MouseDown MouseUp 都有可能触发MouseMove

[堆代码的爱因斯坦]

webBrowser1_DocumentCompleted

WebBrowser1.Document.MouseDown += new HtmlElementEventHandler(Document_MouseDown);

能详细些吗？ 怎么让MouseUp 或down一下，就响应一下
