Imshow not showing image on windows, but it works on mac

Hello,

I am trying to compare some data with a video using imshow. The goal is to go through the data and the video at the same time. A video is playing in subplot(2,1,1), while the algorithm goes through the data in subplot(2,1,2).There is a jpeg file of the plot in the attachment. A friend made a program that works on his mac, but the same matlab file doesn't work on my windows pc. We both use matlab 2015b.

My problem: The figure is not showing. I can stop the file from running and then the figure (attachment) pops up, but I can't see it while the file is running.

Here is some part of the file: (if you want i can put the whole file with the videos on a dropbox)

 for k =1:5:700

    %tic % start timer --> end = toc
    subplot(2,1,1)
    frame= read(VID,initialframe+k-1); 
    imshow(frame(y(1):y(2),x(1):x(2),:)); 
    subplot(2,1,2)
    hold on

    xmarkers = begindata*fps + (k-1); %begindata = prompt%begin*fps+(k-1)+5*fps; %129.5 is zijn start 
    % place markers at these x-values; %2
    ymarkers =currentdatanew(round(xmarkers));
    plot(tnew,currentdatanew,'b',xmarkers/fps,ymarkers,'g*') %xmarkers begin!!
    isgyr = 1;
    xlim([xlimits_L(swimmer)+(k/fps),xlimits_H(swimmer)+(k/fps)-150])%xlimits_L(swimmer)+(k/fps)
    ylim([-3.*isgyr,3.*isgyr])
    hold off 
end

I hope someone can help me. Thanks in advance!

It sounds like you need a call to drawnow.
