I have one that that is just called morse.exe. It is a single file that does not install anything. It is freeware with no license requirements. If you want to PM me with an email address I would be happy to email you a copy because I don't remember where I got it.
If you don't like it, just delete the file and it's all gone. It does not install anything on your computer.
Well, if crime fighters fight crime and fire fighters fight fire, what do freedom fighters fight? They never mention that part to us, do they?
