Hi Eric,

Thanks for your answer!

I updated org (again, now it's Org-mode version 7.5
(release_7.5.461.g6d18)), I switched to Emacs 24 but to no avail. I also
tried to use the debugger but this does not seem to be an error...

Debug on Error enabled globally
executing Maxima code block...
executing Maxima source code block
maxima --very-quiet -r
'batchload("c:/Users/weiss/AppData/Local/Temp/babel-209000BH/maxima-20900VN1")$'
nil
Code block evaluation complete.

I also realized that the 'error message' changes every time I try to run
the code block:

#+results:
: incorrect syntax: / is not a prefix operator
: incorrect syntax: aLH is not an infix operator
: incorrect syntax: hCp is not an infix operator
: incorrect syntax: Premature termination of input at $.
: Maxima encountered a Lisp error:
:  parser: end of file while scanning expression.
: Automatically continuing.
: To enable the Lisp debugger set *debugger-hook* to nil.

This message is 'related' (see lines 3 "aLH is not an infix operator"
and 4 "hCp is not an infix operator") to the following Maxima call
("aLH/maxima-17716hCp"):

maxima --very-quiet -r
'batchload("c:/Users/weiss/AppData/Local/Temp/babel-17716aLH/maxima-17716hCp")$'
nil

Unfortunately, my elisp knowledge is too low to understand what's going
on in ob-maxima.el. Is it a MS-Windows-thing ('/' vs '\')?

To be honest, running Maxima in org in not so important for me. As long
as R works, everything is fine :-)

Thanks,

Bernd
