Why can't I change the right margin in Pages?
I am using Pages 5.5.2 under OS Yosemite 10.10.2 on an iMac. I chose "Informal Letter" as the style, because I am trying to write a SIMPLE letter. It says the right margin is set to 0.5 inches, but the program WILL NOT allow the text to go beyond 6.5 inches. I have turned on the ruler and when I click in the paragraphs there is a blue upside down triangle in the upper ruler showing the limit of the text. If I click on that I can move it to the left, but it WILL NOT let me move it to the right. It forces the text to end at 6.5 inches from the left margin leaving a huge blank area on the right side of the page. This is ridiculous! In WORD it is extremely easy to move the right margin to the limits of the printer. Why won't Pages allow me to move the text limit of the line past the 6.5 inch mark?
HELP!
iMac, OS X Mountain Lion (10.8.2)
