some internal error while zooming any plot

Hi, I'm encountering the below error when I try to zoom any plots. can anyone tell how to overcome this error . I'm using matlab R2016a

Error in ispref (line 45)
exists = logical(exists);

Error in addpref (line 28)
if any(ispref(group, pref))

Error in getpref (line 99)
       addpref(group, prefCell{i}, defaultCell{i});

Error in zoom>locGetMode (line 507)
    hMode.ModeStateData.DoRightClick = getpref('MATLABZoom','RightClick','off');

Error in zoom (line 247)
hMode = locGetMode(hFigure);

Error in putdowntext (line 145)
            zoom(fig,'inmode');

Very strange. This part of the message tells exactly, where the problem occurs, but not what the problem is. Is this really the complete message?

yes ....I get the same error even when I try to edit the plot

I had more or less the same error message, and in my case it turned out to be due to how I had named files in my directory. More specifically, I had an .m file called "zoom.m" in the directory, and that filename was probably causing conflict with internal functions.
