I'm not sure but I think you can't do the same thing, from right to left.
Hype works with Left-top absolute X Y.
You can extend any opject from left to right ( and from top to bottom ) but not the other way ( with the right side fixed) . I tried time ago without succes but not with Hype 3.5.
This is a new option, try again with this option unchecked
I'll try, thanks
