Every once in a while the interface on the ubuntu box becomes unresponsive. The box has natty installed. The main menu on the top left and the taskbar icons on the top right cannot be clicked on. The only thing that can be done is to close any running applications and restart the system. Is there a more elegant solution? Somehow, this aspect of restarting the entire system just to get a functioning interface defeats the purpose of using linux.
Any help is kindly appreciated.
