I just tried it again and got a similar error.  There are three .tem
files sitting in the folder which I can't access:

3472150697.tem
3472154034.tem
3472163064.tem

? (CCL:OPEN-FILE-STREAMS)

ISO-8859-1) #x9EF3246>)
?

The backtrace from weblocks has this in it:

(44380620) : 7 (%CREATE-FILE
#P"c:/usr/local/asdf-install/site/weblocks-stable/pub/stylesheets/vzn/3472163064.tem"
:IF-EXISTS NIL :CREATE-DIRECTORY T) 599
 (44380644) : 8 (GEN-FILE-NAME
#P"c:/usr/local/asdf-install/site/weblocks-stable/pub/stylesheets/vzn/pagination'.0'.css.gz")
191
 (44380658) : 9 (MAKE-FILE-STREAM
"/usr/local/asdf-install/site/weblocks-stable/pub/stylesheets/vzn/pagination'.0.css.gz"
:OUTPUT (INTEGER 0 255) :SUPERSEDE :CREATE FILE-STREAM :DEFAULT
:PRIVATE T) 999

So that must be what is happening.  There is already a temp file there
that was marked for deletion, and then it tries to create another one
with the same name, giving the error.  Since it has been marked for
deletion, then I am assuming that is why I can't access the file
through windows explorer.

Is it possible to override GEN-FILE-NAME in ccl-init.lisp, and add an
extra condition to test for "Permission Denied"?

Thank you very much for all the help thus far.  -John
