i’ve run into so many problems using \_xscale and \_yscale that i’m going to try and re-approach my idea here… .

i’m scaling a box to the size of the browser using this code

```auto

targetClip._height = Stage.height-100;
targetClip._xscale = targetClip._yscale;

```

but when i try and use the box.\_width or box.\_height it’s spitting out the original width and height and not the new scaled width and height.

How can i calculate the new size of the scaled box and/or stage WITHOUT using \_xscale or \_yscale?
