The annotation doesn't quite match what's defined in the script. Take the "Make Decision" button:
/items = ("Make Decision")
/size = (25%, 5%)
/ fontstyle = ("Arial", 3%, false, false, false, false, 5, 1)
/ txcolor = (white)
/txbgcolor = blue
/hjustify = center
/vjustify = center/position = (75%, 90%)
/erase = false
This element, however isn't aligned relative to the left margin, so it's left border is *not* in fact at 75%. The *center* of the blue rectangle is what's at 75% (/halign = center is the default behavior, for alignment relative to the left margin set /halign = left).
(The red line in the above is at 75%.)
So, if you wish to push things further out to the right side of your screen, all you should have to do is choose larger values for the respective elements' horizontal positions. Or am I still missing something? Sorry, it's not quite clear to me what the perceived problem and desired end state are still.
