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.

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