Problems with the gotoAndPlay-function

Hello Im about making my first website in flash. I have animated the
interface now, but suddenly it seams like the

gotoAndPlay();

doesn`t work anymore. It makes the frame which is intended, but it want
play from there unless I use a

play();

in the frame.

I made a new scene with a simple tween to test from scratch but the same problem goes there.
I have attached this tween so you can try it out. If the file works fine for you perhaps the program has to be broken or some sort!?! I uninstalled and installed again but the same problem was here :skull:

couldnt open the document:S

Could be that im in uni and they have flash mx.

I’ll check when i get home.
