Can't Select Command Window While Program Runs

Hello!

I currently have a program that takes about five minutes to run. Within the program I have a counter so that I can monitor the command window to be sure I don't get stuck in an endless loop. For some reason, when my program is running, I am unable to select the main MATLAB window. My workaround right now is to hover the mouse over the preview in Windows 7, which fills up the screen, but I have to keep the mouse there the entire time.

Currently the program generates some figures, but I'm not sure if that is part of the problem.

Thank you for your help in advance, and I'll be more than happy to provide more info!

doc drawnow
doc pause

Any of them should allow you to see what's going on.

Try this code:

t = 0:pi/20:2*pi;
y = exp(sin(t));
h = plot(t,y,'YDataSource','y');
for k = 1:.1:50
  y = exp(sin(t.*k));
  refreshdata(h,'caller') % Evaluate y in the function workspace
  drawnow;
      pause(.1)
end

Now comment the pause line

    t = 0:pi/20:2*pi;
    y = exp(sin(t));
    h = plot(t,y,'YDataSource','y');
    for k = 1:.1:50
      y = exp(sin(t.*k));
      refreshdata(h,'caller') % Evaluate y in the function workspace
      drawnow;
          %pause(.1)
    end

Now comment the pause and drawnow line

t = 0:pi/20:2*pi;
  y = exp(sin(t));
  h = plot(t,y,'YDataSource','y');
  for k = 1:.1:50
    y = exp(sin(t.*k));
    refreshdata(h,'caller') % Evaluate y in the function workspace
    %drawnow;
        %pause(.1)
  end

Do you see any difference?
