    I have an American laptop and I was testing out pykelogger. It seems to log every key press fine except when it gets to the point where I entered my passwords for Skype and Google. Instead of my key presses for my password the logfile displays only characters 0-31 from this ASCII table: http://www.asciitable.com/

    Does anyone know why? I used Notepad++ to display the logfile.
