Windows Notepad

Notepad is easy to use. Used it for several months. But at times when a piece
of script is uploaded - - - copy and paste - - - it takes in the script ''three'' times. Am not aware of this more-than-required-in-take. After few days while
working on the file or folder am confused coz of the repetitions.

Why does Notepad copy, at times, thrice ?

Now am using Word Pad ... works wonderfully well.
