错误信息：Rainlendar seems to be already running

开机出现错误信息，如下：

Do you want to start another instance？
Rainlendar seems to be already running. You can start another instance by selecting ‘Yes’.

出现这个提示一般是在ubuntu退出时强行关闭了Rainlendar2进程所致，重新启动后Rainlendar2以为有个Rainlendar2在运行。

解决它需要在Rainlendar2命令后加个”-m”参数。打开Sessions Preferences会话，在Startup Programs里选择rainlendar2，编辑，在Command编辑框中输入 “-m” 参数。

/usr/bin/rainlendar2 -m

保存后退出，再次启动ubuntu系统提示消失了。
