Weird doubles in "on enterFrame"

Question

I have striped my projects in order to nail down a problem to the bare 1 movie script with:
on enterFrame
  put _movie.frame
end enterFrame
And for some weird reason, I consistently get doubles like this in the Msg window:
-- 1
-- 1
-- 2
-- 2
-- 3
-- 3
-- 4
-- 4
I tried doing a new movie from scratch just to check, but it seems fine. Why would that
happen in my old movie? I checked tempo, doesn't change anything, removed xtras,
double checked some preferences that might influence but nothing.
If you have had this problem before and found out the source let me know,
Thank you
I have this with Trace on:
== Frame: 1
--> put _movie.frame
-- 1
--> end enterFrame
--> put _movie.frame
-- 1
--> end enterFrame
== Frame: 2
--> put _movie.frame
-- 2
--> end enterFrame
--> put _movie.frame
-- 2
--> end enterFrame
== Frame: 3
--> put _movie.frame
-- 3
--> end enterFrame
--> put _movie.frame
-- 3
--> end enterFrame
What on earth causes this?

Try changing your handler to this:
on enterFrame me
  put _movie.frame, me
end enterFrame
I am guessing that you created a behavior and attached it to a sprite, and then you later changed that behavior to a movie script.
If I am right, then you might see something like:
-- 1 <offspring "" 4 532f770>
-- 1 <Void>
-- 2 <offspring "" 4 532f770>
-- 2 <Void>
The sprite receives the #enterFrame event and prints out the frame number plus its value of "me", then the same script receives the #enterFrame event as a movie event, but this time the value of "me" is VOID.
However, this interpretation depends on you have at least one sprite in your barebones movie, in addition to your movie script.
Another possible suspect might be a timeOut object, which can send additional movie events to behaviors, but that does not fit the description that you have given.
