发现一些bug

作者我反馈下我碰到的问题，我用的版本是1.0.0！有时发送消息时显示netty断开，需要重启才能成功发送消息！点击聊天对话界面的＋号和心形图标总是没响应！查找用户名添加好友，搜索用户出来后点击添加看不到好友！重启也一样看不到联系人，都是显示那个蓝色的驴的图片！内置的浏览器查看网页，比如“关于”选项里右上角的“github”点击打开后是正常显示网页内容的，可加载完成后又出现了那个驴的图片！下滑页面刷新后看到网页又一下子变成了那个驴！

No files, tests, or entry points are named. Start by reproducing the reported messaging, add-friend, and in-app browser failures on version 1.0.0; done would require isolating and fixing each behavior and verifying that messages send, contacts appear, and pages remain visible after loading and refresh.
