actionscript 3 - Flash IDE and AS3 Blank Space -

I was working on the file 'as' and then ctrl + entered the project only one thing that I see It is empty space before the test was completely functional and visual. Is there anything about 'flay' size or something?

There is a mouse event in the very beginning and it does not go to the event function.
