No arguments to diff

[Aaron Yoshitake]

Hello,
Whenever I run the diff.exe file with no arguments, I get the correct
messages about not having enough arguments, but then my command prompt stops
responding, and the program never terminates, making me close it. This is
quite irritating, since I lose all the information in my command window
prior to using diff. Is this a known problem, or something wrong with my
system?

Thanks,
Aaron
