Sorry about mess above.
I am using RW 7 (7.4)
I can align the text to the center, and to the right. When I align the text to the left, the edit view will appear correct then when I go to preview the page the text is centered. See attached images.
I have copied the text into Textedit as plain text and then pasted it into a new text box and the format aligned left will appear centered.
