Problem with figures causing Matlab to stop responding?

Hi, I have a problem with plotting figures in MATLAB - particularly multiple subplots. The program stops responding and it appears to be looping within a file called 'doEnablePlotListeners.m'. I can pause within the code but if I then try to quit debugging to get out of the loop it just carries on. There is a comment at the top of the file 'This undocumented function may be removed in a future release' - I'm running 2016a. Will updating to 2017a help or is there something else I should be doing? Thanks for any advice.

Is this constantly happening? I have had numerous issues from time to time with Matlab GUIs but also just Matlab in general getting into some weird state like that in some function I know nothing about and didn't call myself. Usually just restarting Matlab fixes it though and they aren't all that common for me.

Also does your code explicitly use listeners in any way?
