I think it started to behave like this since i installed the 2014 edition.
i removed CC already since i thought don't need it anymore - very confusing this CC and CC 2014 stuff was both there.
Now - when i open Indesign for a few seconds it responds normal but then after few seconds its not responding properly - it behaves like a crashed program (using windows 8.1 64) - when moving away and back to the task, it takes 10 seconds till the UI appears.
when trying to click a menu item, it takes 5 or 10 seconds till something happens.
thought maybe its the plugins but i deleted all and reinstalled indesign fresh from cloud desktop tool and the problem is still there.
i have no idea what else to try - anyone?
Thanks for the tip - unfortunately i have tried this before already - now again - doesn't change anything...
