I use system.totalMemory to listen the memory-allocation  
1)  
I made a button and when clicked the button it would new a Shape and call its graphics method to draw vector lines and then addChild. But it is strange that when I click it first and the lines are drawn, the memory difference is 0. Then another more click, 0 too, and the third one will bring a “0.00390625M”(I divided the number by 1024\*1024 to turn it to “M”) cost.

1. I add a mc to a dynamic class, as:

The output is  
8724480  
[object MovieClip]  
8728576  
undefined  
8728576

Why after adding a MC, the memory is even more !?  
and delete the MC did not make more…

It’s so strange that I don’t know what is wrong !  
Anyone talks about it ? Thanks in advance!
