Empty MovieClips and their size
I have an empty movieclip on the stage at 25, 23.
I have another clip that contains 3 clips at 0, 0.
These 3 nested clips all have an empty 1st frame. Their width and height properties are all 1, 1.
(We all know that an empty clip defaults to 1px x 1px but should that be 0px x 0px? It's EMPTY.)
If I select either of these clips on the stage, I get the proper width and height as reported by Flash.
I get the following:

So what Flash thinks is that the combined width of these clips is 6,710,861 pixels and the combined height of these clips is 6,710,863 pixels?
That's a lot of pixels. And why aren't they they same? I suspect that it's adding 2 pixels for the y position.(confirmed) STRANGE DAYS.
