No need to be obnoxious. I do appreciate your efforts to help, but you
must admit, your last statement is a bit snide and certainly not
useful. I'm telling you that the code runs differently on my laptop.
Why this is, I don't know any more /or/ less than you do apparently.
Now, it is of course possible that I'm interpreting the results
incorrectly, but that doesn't change the fact that I'm getting
different results per computer with identical code.
