Mx tweens not stopping @ the correct widths / heights

I have a simple width and height I am pulling from an xml file, when I trace it out, it shows correctly, but when I tween the width and height it doesn’t quite stop at the correct widths and heights. The width and heights from the xml are 800 and 600.


new Tween(c, "_width",	btnEase, c._width,	w, 1, true);
new Tween(c, "_height",	btnEase, c._height,	h, 1, true);

When the tweens stop, the widths and heights are off by anywhere from 5 - 10 pixels.

Anyone ever have this problem?
