Did you do a restart of the app, so that inDesign could write new defaults to its preferences?
Closing the file should change defaults for new docs, but it wont affect anything that already exists. You change the defaults in existing files by making the changes with nothing selected.
Have since found that problem occurred due to migrating V6 files to new machine with v10cc. To fix I had to copy text etc. to new pages generated in V10cc. Thanks for your input
