I am trying to insert a text box onto a page using workflow. The activity has built in location placements which seem to work. However, I want the top/right placement to be top/right:

What I get is top(ish) right(ish):

So I used the custom placement and no mater what I make the x/y coordinate values I get:

What values would I need to use to get it in the upper most right corner? And why do any changes to the x, y coordinates give me the same result every time? Help! Thanks!
