Luckily this isn't too hard to fix, but should probably be mentioned in  
the manual since it had me puzzled a bit when testing pal on CLisp.
For some reason CLisp runs by default in non-ANSI compatible mode which  
causes problems like that one mentioned above. To fix it either:

1) Set custom:*ansi* to T after starting CLisp
2) Put (setf custom:*ansi* t) in your .clisprc file
3) Start CLisp with the -a command line argument

That _should_ fix, let me know if still doesn't work.

PAL should work fine on Windows, with either or SBCL or CLisp. Allegro and  
Lispworks are less tested but in theory there shouldn't be problems.

After loading PAL try (load "<pal-dir>/examples/teddy.lisp") and  
(pal-example::example) from REPL. If that works it is very likely that  
everything is working correctly. You could also try the "polygons.lisp"  
example, it should start automatically after loading.
If you have more problems let me know :)
