Every so often my computer refuses to start and, when I press Ctrl-Alt-Del I am told that Ccapp has not finished what it is doing and I can either wait until it has or press another key to continue. Whatever I do nothing happens and I have to switch off at the mains and start again, usually with some success. I have no idea what Ccapp is and so cannot decide whether or not to delete it. Can you help? Bottiman.
