Disclaimer I only use InDesign a couple times a year and google most steps.
I made a 5 column layout in master pages to place contact info for about 1500 in a membership directory. Starting at A I went through adjusting info and type as needed. Everything was fine until the final page when the type was inserted the columns shrunk to a fraction of the page.
I've tried adjusting the size of the text box, over rides etc, to no avail. I took a screen shot when helps explain. Using CS6 Any help would be greatly appreciated.
Trial and error, figured it out. I over rode the master, turn off auto size in text frame options and was able to resize.
