Thanks. Just to see how that functions I changed the code to:

 (defun my-file-browser ()
   (let ((fname (anything-c-read-file-name "AnyPrompt: ")))
       (message "FILENAME: %s" name)))

Calling that yields the following error message:

anything-compute-matches: error when processing source: 
Read file name (`C-.':Go to precedent level)

Next I used the Anything menu (Anything->Find Files) to see if Anything
would work when run normally. It did. On a hunch I tried the above code
again and it also worked. Then I checked and found that Anything->Find
Files doesn't even invoke anything-c-read-file-name. After that I exited
Emacs and was able to repeat everything several times in a row.

Ah, well, mysterious things happen when you use functions that weren't
intended for external use. I'll just mess around with this until it
works.
