How do I Window width letterbox scale

When i set the game to letterbox scale my calculations such as set an objects scale to window width/2 are out of sorts. why is this? is there a work around?

I'm not sure why that is, but I always use the ViewportLeft(), ViewportRight(), ViewportTop() and ViewportBottom() expressions

So instead of Window width/2

I use

0,5*(ViewportRight(0)-ViewportLeft(0))

Thanks a bunch little stain. I will try this later today!. Cheers m8!

Works great! thansk little stain.
