Where do I start, generally Illustrator, Indesign, After Effects are all buggy and unreliable, especially frustrating when these are supposed to be professional apps and we are charged accordingly.
After a certain amount of time, will no longer allow you to save, forcing you to export into a different format and restart.
Also, the import command is unreliable at best.
Crashes and has a major memory drain, even when editing vectors.
Crashes parts of the UI stop working. Ram playback errors make it unusable at the moment.
I'm using a 12 core mac pro with 64GB of Ram
You've been transferred to the InDesign users forum (just InDesign).
InDesign usually works well, but you'll have to give us more details – your InDesign version number and operating system etc.
In the meantime try trashing your preferences, if that doesn't work come back here with more info.
