i think i might have faced the same problem... i have 2-3 words (depends on how you want to see it, actually there are 3 in my case) and it's not accepted as solution... i wanted to try again, after having my mind cleared. i then forgot about it, but now that i crossed your post, i had to run my script again...
so, just to take part in this inquisition :)
is it supposed to be the solution? (or part of it?) or is there something _we_ missed?
