waitfor function not working properly.. need help

Hi guys,

I used the waitfor function on matlab 2013b and now that i have installed 2015b, this function does not seem to work properly.

Firstplot= plot(thld,numBlackPixels); %plots each thld value and its corresponding black pixel count
grid on
xlabel('threshold')
ylabel('BlackPixels')
zoom on;
waitfor(gcf,'CurrentCharacter',13)
zoom reset
zoom off
[x,y]=ginput;                        %lets users select the range of values for thresholding 
x1=x(1);                             %first x value chosen
x2=x(2);                             %second x value chosen

The above line of codes is what i've been using in 2013b and it doesn't work in 2015b.. i get the error

Error using waitfor
Invalid property.

Error in Image_Analysis_For_Porosity_And_Cracks (line 27)
waitfor(gcf,'CurrentFigure',13)

I cant figure it out. Thanks for the help

waitfor(gcf,'CurrentCharacter', char(13))

thank you. That was a silly question but thank you

It was not a silly question. I just happened to test on R2016a that had a much clearer error message for this case.
