IDE：IDEA Commit Changes Dialog local changes refresh

IDEA提交代码，一直卡着不动，显示：Commit Changes Dialog local changes refresh

修改方法为：

1. go to settings - version control - background
2. set changelists to cache initially to minimal value (10)
3. check setting refresh changes every
4. set huge value for minutes (240 for example)
5. save settings
6. reload Idea
