Maya be this is not the kind of help you are looking for but Illustrator does this very easy and perfectly. Its text tool when position over a path line will create text along the path. I don't know Flash very well yet, but I don't see options for text along a path in the obvious places of the interface and there is no mentioning about this in the online help.
that's kind of what i'm looking for, but in Flash. Do you by chance have a picture of what tool you need to use in Illustrator?
This is a link to the Illustrator help
and also a link there to a video:
