I have a vertical line in a Movie Clip. On my stage the height is 55, but when I compile and trace its _height, it returns 57.

I found that the line's thickness has something to do with this. When the thickness is 2, the height of the line on the stage increases by 2 when I compile the movie, and when the thickness is 5 the height increases by 5, etc. It's as though the line's height is determined using: (Line Height When Compiled) = (Line height on the stage)+(thickness of line).

Am I missing something here? Please let me know what I'm doing wrong. This is bizarre. If I need to explain better let me know. Thanks!
