Creepy. I'd suggest reporting it to Adobe ().
app.activeDocument.pageItems.everyItem().nonprinting = false;
(Okay, just tried and it does work on master page items. Oof!)
thanks. I have to admit i don't have experience with scripts. can you indicate what should I do with this beautiful prose?
(You can read a longer description of the same steps in http://indesignsecrets.com/how-to-install-scripts-in-indesign.php.)
... I'm so used to using scripts, I always forget modern InDesigns can do things now that one had to do by scripting in earlier versions ...
If the scripting route doesn't work for you, try Find/Change Object. Under "Text Wrap & Other" (!) you can find "Nonprinting".
really. I do thank you a lot. it worked absolutely fine.
for a uninitiated person, these scripts are like magic spells.
wish there were scripts for real things in life.
