Here’s the thing

I am working on project where:  
[LIST]  
[_]A rectangle is rotating. Think of a clock. Programmed with a tween.  
[_]There is a generator. On click it produces a square, duplicate of a movieclip. This square can be dragged across the screen. The code for dragging is written on the original movieclip which is not on scene. Generator and square are different movie clips  
[_]I want to program a collision detection between the square and the rotating rectangle.  
[_]The hitTest function doesn’t work. . I have programmed collisions between moving objects before (bullets/enemies) and I can’t figure out what’s wrong.  
[/LIST]  
Help is more than appreciated.
