Hi,

I’m very new to flash, but the turtorials on this site helped me a lot.  
I still have some questions which somebody might be able to awnser.

- How to create an symbol/line (whatever) that changes from alpha during a motion tween ?
- How can i make lines that I can see in Flash mx, but not in the movie itself ?  
Transform a layer to a guide or something ??
- and, Ho could i possibly make a dot that moves with a motion guide but it should leave it’s track. ?  
I hope you can understand my english 😛

Gr, Dirk
