Set the stroke style of the line to “hairline”.

are u doing this with vector objects that u made, ie: a vector box or like regular lines, then chances are, u are using movieclips for vector graphics animations, basically, ur supposed to use graphic symbols with vector stuff thats made in flash, otherwise if u made for example, a box, make sure u put the border instead of “Solid” to “Hairline”. So basically, when u stretch the box, the lining will stay the same, and wont get thick, also remember to convert the vector object to a graphic symbol. Try this out, and reply back with the results.
If you dont convert ur vector motion-tween work to graphic symbols, and for example convert a box into a “movieclip symbol”, u’ll notice that when you motion-tween those objects, the border lines will get thicker, and if thats what u are talking about, the above statement could be a solution.
