MATLAB: Editor doesn’t run .m file

Question

I'm using Matlab r2008b. I can open my two .m files with the editor (the main program and the function), but when I click on RUN, nothing happens (However, it was working last week). The command window stays empty, no error message appears. After that, in the command window, I write for example :

a=2 
clc
close all 
clear all

Still nothing happens! The command window stays with the text. I have to close everything for Matlab to work again. Then, when I run other .m files, it works. I'm the right directory. The .m files have simple names.

Please help!

Does the status bar say "Busy" or "Waiting for input"?
