ginput not working with R2015a for handling two figures

I have two open figures in MATLAB and I want the user to be able to get graphical input from both the figures, by calling ginput on one figure at a time and switching control between the two figures. I have the following code that does this, which works perfectly well in R2013a,b:

h1 = figure;

h2 = figure;

h = h1;

while 1

      figure(h);

      [x, y, sig] = ginput(1);

      disp(['x is ' num2str(x) ', y is ' num2str(y) ', sig is ' num2str(sig)]);

      if sig == 49
          % 1 has been pressed
          h = h1;
      elseif sig == 50
          % 2 has been pressed
          h = h2;
      elseif sig == 3
          % Right click pressed
          break
      end

end

The above code starts with calling ginput on figure h1 and keeps receiving graphical inputs until 2 is pressed, which switches the control to figure h2. Pressing 1 switches the control back to figure h1. Pressing right click terminates this operation.

When I run this code in MATLAB R2015a, a stale crosshair appears on figure h1 which neither receives any graphical input from ginput, nor allows the user to switch between the two figures.

Has anyone else encountered a similar problem while using ginput in R2015a? It would be great if someone can find a solution to this problem.

Thanks,

I have the same issue. Very like your problem, I am calling ginput sequentially in figure 1. However, I then plot something in figure(2) before going back to figure(1) and calling ginput and it fails. This code worked fine in previous mntlab versions

I have just called technical support and found the work around. It's a known bug and to get round it, after every call to a new figure (or probably any figure) you need to call drawnow
