问一个关于swing的问题，有没有见过ActionListener,MouseListener这两个事件冲突的？

package socket;import java.awt.*;

import java.io.IOException;import javax.swing.*;public class UserUI extends JFrame implements ActionListener,MouseListener {    public boolean notshow = true;    private JLabel email = null;

        this.addMouseListener(this);
        //        this.addMouseListener(new MouseAdapter(){

}主要目的是在这个窗口有鼠标enter就不做处理，当鼠标exit的时候需要设置为不显示。下面的email按钮是调用本地发送邮件，可是在鼠标滑过按钮的时候，窗口就被设置为不可见了。将email改为label就可以，但是触发不了发送邮件啊？其实最理想的就是email用超链接的形式/
