[color=blue][font=Verdana]Hi there,[/font][/color]
[color=blue][/color]
[color=blue][font=Verdana]Just a quick newbie question …I read the course outline of Macromedia on Flash Basic and under building a Navigational sys there was a sub-category on “[/font][/color][color=blue][font=Verdana]Using a MovieClip as a wrapper”.[/font][/color]
[color=blue][/color]
[color=blue][font=Verdana]What does it mean when you make a movieClip as a wrapper? does it mean movieclip buttons? Just confused on that part. I tried to check out some books but have failed to find the exact “term/wording” that refers to movieclip as a wrapper.[/font][/color]
