Keep stroke weight while changing width

programming flash
1

Hi guys,

I have a movieclip ‘cursor’ with in it two rectangles. One of them is dark and one is light, so the cursor is blinking. Now, when I want to change the width of this cursor to 150 (where it was 30 before), I do:

cursor.width = 150;

This not only changes the width of this movieclip, but also the weigth of the (whole) stroke of the two recangles. How can I prevent this strokechange from happening?

Thanks in advance!
