I want to bring this back up because I also have this problem.

Hi all, I am experiencing the same issue with the same error message. It started when I first used Ctrl+C in Live Script to copy a part of my script. Would like to hear from someone on how to fix this.

Hi, I have the same problem. Within a Live Script copy and paste does not work. Any ideas?

The problem seems to correct itself overtime, i've not had the problem in a while and i haven't made a significant change to my MAtlab since then, except updating my Java.

I had the same problem.

I don't know why but increasing Java heap memory fixed the problem.

Thanks for your response Ra, but i tried it again this morning after updating my windows and the problem seemed to vanish, strange stuff.

on a side note, If anyone still has this problem, i think it might be a result of having more than one matlab versions installed (in my case i had the 2016b, upgraded to 2017a then 2017b).

For diagnostics i'd recommend you open the other versions and see if the same problem persists on your other matlab versions, if it doesn't exist on your other versions then i'd recommend you re-install the matlab version with the problem.
