Size of sprite different in AS3 and Flash

Question

When i do a Select All of my symbol in Flash I get a height
(lets say 300x300). Even if there are multiple items, it groups
them together to give me the total size.
In AS3 I never get the same size. I have tried calling
getRect(), width/height, etc... I get a different size, it's close
but still invalid, sometimes smaller, sometimes larger.
To replicate this:
1. Create a new sprite with some text, add some paint
brushes, etc..
2. Add the sprite to the stage and notice its width and
height
3. Give the sprite an instance name (in this case I called it
"block")
4. Add a document main source file and add the following code
to the constructor (from the bottom of the script)
You will see that the size the code tells you and the size
the flash editor gives are different. Is this a bug?

Answer 1

1) yes the sprite is on the stage. It is accessible by AS3
just the size is wrong.
2) no, the sprite is not always a whole pixel, sometimes the
size in Flash may be 300.50 x 210.90 etc..
