Event loops entanglements, I suppose.
The code code runs fine in IDLE on Linux.
I'll try to fix that up (if I can), before the beta.
If anyone has experience (or would like to gain experience) with this
sort of issues on WinXP, please do not hesitate to step forward.

Do you mean "/include/R" ?
If yes, that might be a little too exotic for the current setup.py (the
setup.py is still a little rough, and will not cover a number of
situations).
Try editing to your liking the line in setup.py that goes like:
include_dirs = [ os.path.join(RHOME, 'include'),
(so tentatively:
include_dirs = [ '/include/R',
)
I'll see how I can improve setup.py to either have an automatic
detection or allow a manual specification of the directory.
