Another thing you can do is create a text file in the same folder as the grisc program. Type just the grisc command into it (not the 'cd c:\somefolder') just as you would do in the dos window. Now save the file and change it's extension from .txt to .bat
Now just double-clicking on the .bat file will do everything, and it's there for future use !
(this works for any command you can type into a dos window)
