I have Indesign CS6 and the save, save as and export options get greyed out. I have to restart indesign holding shift, control and alt to delete my preference file. It seems to happen randomly with different files. Sometime is can be a file with text and eps files and sometime it can be a file with just a png or jpeg in it. What can be causing this? How can I prevent this?
I ma on a Windows 7 machine with 4GB ram and 360GB of free space on the hard drive.
Do you use the Chrome Browser? If yes, remove the browser plugins (particularly PushBullet)
No, I do not have Chrome installed.
Too bad, since that's about the top of the list for things that cause this. Some Firefox plugins cause trouble, too.
How about a font Manager? Turn of the auto activation plugin (or remove it entirely for testing). Could also be your anti-virus, but less likely.
Does it happen if you create a new user account and log in with that?
