I had to reinstall Deepin 2014.3 and there were no problems with it until i updated it via the sudo apt-get upgrade command. Now it does not matter that i use the bottom right hot corner or the sstem settings icon from the dock, the settings panel does not show up. I even tried to remove the desktop enivronment with it's configuration files and reinstall it, but it didn't help. Here is the list of updated packages and here is what i see when trying to launch dde-control-center from terminal.
