Why is the pause button interfering with the exit button when pause is pressed?

So far I have the code below and need help with the button because it just pauses and will not continue and I can only press pause once per open Matlab.

function nightonearth
% NIGHTONEARTH shows rotating earth by night

% Requires images 'earth_lights_small.jpg' and 

% 'moon.jpg' on the path stars=rand(100,2);

%Line 10 is for moon
[x,y,z] = sphere(48);

x2=(x*0.2734)+1;

y2=y*0.2734;

z2=z*0.2734;

f=figure('Color','k');

staraxis=axes('units','normalized','position',[0,0,1,1]);

scatter(stars(:,1),stars(:,2),'w.');

axis off 

earthaxis=axes('units','normalized','position',[0,0,1,1]);

hold on;

s=surf(x,y,z);

s2=surf(x2,y2,z2);

   %[X,Y]=meshgrid(0:2*pi/60:2*pi,(logspace(0,1,20)-1)./10);
   %[X,Y]=pol2cart(X,Y);
   %Z=X.^2+Y.^2;
   %s3=surf(X,Y,Z);

shading interp

axis([-2.5,2.5,-2.5,2.5,-1.5,1.5]);

daspect([1,1,1])

axis off vis3d

set(gca,'Position',[0,0,1,1]);

topo=imread('earth_lights_small.jpg');

topoud=flipdim(topo,1);

set(s,'facecolor','texture');

set(s,'cdata', im2double(topoud));

[topomoon,map]=imread('moon.jpg');

set(s2,'facecolor','texture');

set(s2,'cdata', im2double(topomoon));

camtarget([0,0,0]);

campos([25,0,0]);

%------------------------------------------------------------------

% fig=figure;

tryme = uicontrol('Style','togglebutton','value', false, 'string', 'Exit');
%------------------------------------------------------------------

%IMPROVEMENT #2: Add another togglebutton to stop/restart the rotation

uicontrol('units', 'normalized', 'position', [.04 .1 .1 .05],...
    'style', 'pushbutton', 'Callback', 'pause', 'string', 
'Pause')

pause on

%^^^ just added this part

%------------------------------------------------------------------

while ~get(tryme, 'value')

      rotate(s,[0,0,1],1,[0,0,0]);
      rotate(s2,[0,0,1],0.0357,[0,0,0]);
  %     camorbit(15,0)
      drawnow; pause(.1)
  %------------------------------------------------------------------  

end

You need a

pause on

call for the pause call in your IMPROVEMENT #2 to work. See http://www.mathworks.com/help/techdoc/ref/pause.html

When you have pressed the button, you need to press a key (not click again) for that form of pause to continue.

I added the pause on and it worked wonderfully, but when I go to press exit, it no longer works. Do you have any thoughts on this?

[Aaron]

I think it just lagged up, but it seems to work now. I thank you so much for your help.

You might be actually looking for uiwait and uiresume functionality instead of pause
