Eclipse里編輯代碼，進度條出現“Remote System Explorer Operation”，導致Eclipse有卡頓。
解決方法：
Eclipse -> Preferences -> General -> Startup and Shutdown.
- Uncheck RSE UI.
Eclipse -> Preferences -> Remote Systems.
- Uncheck Re-open Remote Systems view to previous state.
Update your Eclipse to 4.3.1 (at least) due to a bug on previous version.
Restart Eclipse and its done.
