Ok lets get into it, first click on the circle making tool thingy, i dono what its called but it makes circle, thats what the first arrow is pointing to. then go to the white swear and hold and drag to make the circle as shown by the second arrow. mmm.

Then select the arrow tool that i have shown by drawing a big red arrow pointing at it, have a look and c if u can spot it. then highlight the the circle u have created earlier by holding left click and dragging the the swear over the circle. then right click the highlighted circle and select the option convert to symbol.

You will see this window open up before your eyes, when i learned flash they told me to name everything but i don't and i have never had a problem but you may want to do this to keep your flash organized. just click OK.

Your symbol will now look like this.

Now you will notice the time line as i am now talking about it. right click frame/cell 20 and select the option Insert Key frame. i forgot to draw an arrow so u may have trouble finding it.

The time line will now look like this.

You will notice that frame 20 is high lighted, carney's dick, if it is not high lighted, do so. move the circle to some where els on the white swear as when u play ur movie anything out side the swear is not seen as it moves off screen.

Now right click some where in the middle of frame 1 and 20, the little option list will drop down and select Create Motion Tween.
Now u have completed the tut, u can play with ur creation by clicking the red swear on the time line and dragging it left and right. OR u can just hit Enter on ur key board. lovely
