Memory Leak in using "set" function

I am using windows7, and Matlab R2011b

I have created a GUI, which only contains one pushbutton and one editbox.

In the callback of the pushbutton I have the following script

for i=1:1:1000000

set(handles.edit1,'String',num2str(i))

drawnow

end

When I run the script and hit the pushbutton, the memory rising up to 1GB.

What cause the memory to rise? what am I missing?

How do you measure memory use?

I simply use Windows Task Manager to monitor the memory used by Matlab. It increase up to 1GB.

Any help on that issue will be greatly appreciated.
