How do I ungray a checkbox for this message: always use the selected program to open this kind of file.?

Question

When I try to open a particular file, I right click the file and select "open with". A new window appears asking me to select the program from the list. I select notepad and want to check the box that says "always use the selected program to open this kind of file" but it is greyed out. How can I solve this? Thanks in advance.
