Yes, Wordpad was not best choice, Notepad would be a bit better but still the line-endings should be in unix style (LF) and notepad adds MS_DOS style ones (CR+LF) so even using notepad in not good choice.

Best is to edit in directly on the tablet (vi, mcedit, nano, ..) or if you want to go the windows route you can try pspad http://www.pspad.com/ or Notepad++ http://notepad-plus.sourceforge.net/uk/site.htm

Both tools are pure text editors and can preserve or convert to unix line endings.
