I thought I knew a thing or two about the command prompt of many years ago!
However, I am ashamed to say that I have got into an awful mess:-
1) I foolishly opted for full screen and now I can't get back to a normal window.
2) Worst still, when I enter what I think to be a command and press ENTER, I get
the error message ".......not recognized as an internal or external command....."
If some kind soul could put me straight, I would be most grateful and promise not
to do this too often.
