recently I realize that aftersome time the editor starts to respond very slowly, whcih makes it impossible to continue working efficiently. To resolve the issue, I shut down Matlab and delete the preferences folder. After a fresh start it works again. However, this is annoyinh because I always have to re-initalize my preferences. Does anybody know what the problem is and how to resolve it ? Ii happens with R2018b and R2019b. I have an Imac with 10.14.6 Mojave.
Thanks for your help help.
