spark登陆后闪一下就不见了，问题解决了。

     这个问题困扰了我两天，卸载Dr.COM客户端（我们学校上网要装这个客户端登陆服务器，以后只能在网页里输入用户名和密码了），问题解决了。问题的现象：在实验室机台式机上安装openfire和spark之后一切正常运行，但是回到寝室在笔记本上同样的方法安装配置完成后，spark登陆后闪一下就消失了。

    刚开始以为是系统不兼容导致的，因为两台机子上装的xp版本不同，所以就开始折腾我那脆弱的笔记本，重装系统N次，期间还买了一张xp，装完系统后，任何软件都不装，直接安装openfire和spark一切运行OK，但是随着必备软件的安装，又出现同样的问题，通过定位错误log，其中有句“Problematic frame:# C  [TcpIpDog0.dll+0x6725]”到网上搜索后发现这个TcpIpDog0.dll文件是安装Dr.COM 这个客户端后产生的，直接将Dr.COM卸载，问题解决。
