I cannot explain why, but some layouts I could make a pdf of, and some I could not, but the problem was related to custom menus. When I opened up the menu options for the file menu, the problem went away.
Disabling menu item in Go can create some unforeseen problems. I didn't think about that being the problem until you posted your answer. I had a problem with custom menu and containers fields about a year ago. I just level Go menu items as is.
Glad you figured it out.
