can't get nla strip to use path

I’m trying to get working on nla animations. So far they mostly work except when I try to attach them to a path. I parent the skeleton to a path. When I click N key and push the use path button in the strip property, the skeleton just acts like it doesn’t have any key frames anymore when I press the alt-a keys. Also, the strips that don’t have the use path button pushed use the path anyway. I don’t have the latest version of Blender, I think it’s 2.37.
