Duplicate: Text field of program arguments in code blocks 10.05 is not displayed
I want to debug code that accepts command line arguments in C ++ using the Codeblock IDE.I googled and read that "Project-> Set program aregumnets" can be used to pass command line arguments. But when I select this option, the text box is not editable. Please see the snapshot below for help with your view.

Any thoughts on how to fix this.
Edit:
I'm on Ubuntu. I can log in Program arguments, but I cannot increase the size of the text box. Even a larger window does not help. I can see what I can type.
Reinstallation did not help.
