I try to add a stroke or change the fill to a specific object within a specific document in Indesign and it always freezes. I had the trial version and I have just bought the creative cloud suite. This was never an issue when I had the trial version and no extra downloading was needed when I paid for the yearly subscription. Indesign also became very slow and a few background changes in my Indesign documents suddenly changed when I bought the software. All I have installed on my computer from cc is Indesign, Photoshop and Illustrator. This is no different than when I had the trial version. Whats happening?
What else has changed on your system?
Does it just freeze for a moment or longer? If only moment, then it might be caused by Preflight being activated. Preflight checks the whole document with every change you do.
While editing it is recommended to switch off preflight.
