• 问题描述 | Issue description:
  I guess there is a memory leak issue. I leave my macbook in standby most of the time, in particular at night. So, I turn off completely the external mouse. After a weak of usage, I saw in the Activity Monitor that Mos used 297MB of memory, which is quite a lot. I forgot to make a screenshot before closing and reopening the app.

• 如何重现 | How to reproduce it:
  Normal daily usage, no gaming and no heavy scrolling. Even when you don't use the mouse or the scroll, you can see the memory usage increases.

• 软件版本 | Application version:
  2.2.6

• 系统版本 | System version:
  macOS 10.13.4

• 您系统中的其他鼠标管理软件 | Other mouse management application in your system:
  Nothing, the default system settings.

You can find a little test I did for 2 days, where the night the mouse and macbook are not used at all.
Imgurl screeshots of 2 days

Btw great app!
