Oops - you were right.  cygserver was still running so I shut it down which
enabled me to do rebaseall.

In fact I've now tried all of those things except for checking the Shared
Memory and Semaphores which I don't know how to do.  I've even uninstalled
jack and qjackctl and re-installed them both but jack still won't start for
me.

As an exercise this morning I tried starting jackd from a command line using
this command:-

jackd -m -ddummy -r48000 -p1024

(which is the same command being sent by qjackctl).  Interestingly, after
the copyright messages it produced this output:-

JACK compiled with System V SHM support.
cannot stat() /dev/shm (No such file or directory)
cannot create server sockets
cannot create engine

Sure enough, although I have a folder called '/dev' I do not have a file or
folder called '/dev/shm'.  Does this give any clue as to why jack cannot
start?
