Thank you for the rely.

In fact , I'm going to use the ocTest to build some automatic test.
So I get a Modal Window , I want to show it first ,then close it
automatically . I'm sure that the windowDidBecomeKey method did get called.
Perhaps I didn't describe my question clearly , which leads to some
misunderstanding.


Now I 'm using a NSTimer to call another method to abort Modal and close the
window. It works well.
But I still want to figure out why these wired things happened which like I
described in my question.
