Well, this turned out to be partly my fault, sorry. :-(
PSConfig was written so that you had to pass it a filename and a
directory name. Of course, no one does, probably. They just pass
it a filename that has directories appended to the name. So, I if you
did to that, I was appending something else on to the front of that,
and ... well, it was ugly. So that is fixed.
Then, I just fixed PS_END so the command that I am going to SPAWN
will accept filenames with spaces in them.
You can get all the files you need (assuming you following my
advice this morning and downloaded a new copy of the Coyote
Library), by downloading and installing this file over the top
of your Coyote Library files:

Sorry for the mix-up. It seems if I make one small change in this
library, I have to fix 50. Weird.
Cheers,
David
