The question is :

in the PAST, in my Flash IDE, the rect *WAS* place to "0,0" as its *left-root* to the left root of the scene.

but NOW, the rect *IS* place to "0,0" as its *Center* to the left-root of the scene

I don't know why there's difference between PAST and NOW.
Did I make any action in the IDE , a key-press , or some wrong click in any settings pannel , I've made Flash for 3 years , though my native language is not English , I think i am familar enough with this-English-version of Flash. But this time I really have no idea. :(

遇到一个非常奇怪的问题，在gotoAndplay论坛问了问。

看看能不能结交国外的高手：）
不过我这英文水平和Flash水平，还要狠狠地提高……
