Unable to close CCS if another instance of the same CCS installation is running and using the same workspace folder that the new instance is trying to use. It simply gets stuck at the initialization phase while periodically popping up a message that "The current workspace appears to be in use by another IDE instance". Attempts to close the IDE fail. So does attempting to "Reload Window". This happens even if the first instance is closed. Terminating the process via Task Manager (Windows) is required.
