This is a perplexing issue: a program icon for a RUNNING program disappears from my Mountain Lion (10.8.1) Dock once the documents it was displaying are closed.

The offending App is TextEdit, although I suspect this will also happen in other apps. I'll be editing a text file, then close the window using the red "x" button in the top left, and as expected the window will close and the TextEdit icon will remain in the Dock with the little blue dot underneath. But wait a few seconds, and the Dock icon disappears!

I know that it's still running, because I can see the process in Activity Monitor. So what gives? Does anyone know how to make running applications remain in the Dock?

Thanks in advance.

尝试使用以下任一过程重置扩展坞。

1.打开终端并输入

defaults delete com.apple.dock
killall Dock

或者

rm ~/Library/Preferences/com.apple.dock.{db,plist}
killall Dock

希望这对您有所帮助。
