Thanks for your input; I have made shortcuts on the desktop for the original InDesign folders DEFAULT and SAVED DATA.
A third shortcut, containing the 'fresh' files, makes it very easy to copy and paste these files to their original folders.
I always used the Ctrl-Alt-Delete methode and had to make my adjustments every time from scratch again and again.
Your methode saves a lot of time setting InDesign to my personal specs.
I personally thought it is a memory problem, because after closing and restarting InDesign the problem doesn't occur.
But with 16 gigs on RAM and 4 gids on the graphic card that seems like impossible.
ID is a 32-bit program, so it doesn't use all that excess memory, but I don't think it's a memory problem anyway or it would be all over the forum.
This morning I started InDesign completely 'fresh' with new Default and SavedData settings and immediately the problem occurs again.
Some of the pages don't show their content, but I found out that when enlarging those pages to f.e. 200% the content shows again.
This is unworkable this way and very annoying; it sucks!!!
Are you re-using an old set of prefs that you backed up, or did you get a new set, customize them, then back them up? It's not clear from you post above just what you did to replace them.
The other easy thing worth trying is to export the file to .idml. See Remove minor corruption by exporting
First I generated new files by CTRL ALT DELETE and than made a backup of those new files.
This morning I started InDesign 'fresh' and right away some pages didn't show their content as usual.
I will try your other suggestion to export the file to IDML; possibly it's a flaw in the file itself.
What's the OS?
Windows 7 Professionel (64 bits)
Does it work if you create a new user account and open ID in that?
I don't know Peter, I will try that later and keep you posted.
First I have, on your suggestion, exported the file to IDML and opened it again in InDesign.
For now I have to keep pace, because the magazine has to be delivered at the printer by tomorrow.
Because of this time pressure it is so frustrating that I have to start InDesign again and again in order to see what I'm doing.
