poll results page not generate

Hi To all,
When I enable poll core module it create 3 type of pages:

1. content type pages
2. /poll page ( view of all polls )
3. /poll/%/results ( the results of a spicific poll)

the last one - poll/?/results ( the results of a spicific poll) not generate and get the url node/???/results
How It can fix?
Thanks a lot/
