This is most likely the correct behavior. If you output a binary file to the 
console, it is very likely to include all sorts of random control characters 
and escape sequences. This will change the settings of the console.

If you want to restore default settings, click the right mouse button and 
select "Reset". Alternatively, you can run the "reset" command line program, or 
you can try typing "CTRL-V CTRL-O RETURN" in your shell. The latter doesn't 
always fix all your problems, but it is so easy to type, there is never any 
harm in trying it.
