i'm running the latest cvs but the following most probably applies to  
0.8 too:

"current working directory" (CWD), when you start fluxus application  
bundle (no matter how you start it) will be Fluxus.app/Content/ 
Resources. I'm not sure why, I'm a total macosx noob.

a work around for now (and a handy thing for later) is to add the  
following to your /Users/mashive/.fluxus.scm {assuming your username  
is mashive ;-)}:

(chdir "/path/to/working/directory")

you could also change this config for every performance, so that you  
keep the scripts made live sorted by performance. you could execute  
this command live too, but each time you make fluxus crash you'll  
have to reexecute it.

oh i won't be surprised at all if osx was broken in that way ;-)

but lacking osx experience i wonder: why do you expect CWD of an app  
bundle to be the directory you put it in? i have all applications in / 
Applications and i don't expect them to drop their files there.  
Shouldn't default directory be, for example, user's desktop? i  
noticed that, for example, all pdfs that i view from web browser  
endup on my desktop.


NB: in cvs the "load" was renamed to edit, and i haven't had a look  
at the implementation yet. "source" is gone altogether in favor of  
standard guile's "load" (yeah, the transition may be confusing, sorry  
for having caused that). the following paragraphs below use CVS  
terminology.

in addition to "load" guile provides somewhat handier "load-from- 
path" which searches all paths in the list "%load-path" (+ it also  
tries all extensions from "%load-extensions"). you can configure  
these variables in your ~/.fluxus.scm config file, e.g.:

(set! %load-path "."                ;; CWD
                  "/Users/artm/"
                  "/Users/artm/Desktop"
                  "/Users/artm/fluxus"
                  "/usr/local/src/fluxus/examples")
(set! %load-extensions "scm")

{adjust it to your environment of course}

i'd like "edit" function to search these paths as well (using  
scm_sys_search_load_path). i'm not sure it cares at the moment, but  
i'll fix that.
