Here is the thing… i created this sliding puzzle game in AS3… i must say that i’m new to making things move or any other kind of animation through AS3 code… so, if there are any beginner’s mistakes - i apologize! 
Now, the problem is that sometimes when i click on one piece of a puzzle, and it should start to slide on to new position, it first flickers (if i can call it a flicker) and then moves… i attached the whole project in a RAR file on other forum (this one doesn’t allow more than 150kb) - here is URL (http://www.flashmove.com/forum/showthread.php?p=125861#post125861) … so, anyone is free to take a look… and offcourse - HELP!
there… and one more thing… be patient… it sometimes takes more than 20-30 clicks for it to happen… but trust me… it happens!
thank you all!
