even a simple "System.print" on a button didn't work
My experience since the firmware/software upgrade is that the System.print command does not work using Jon's mod if what it is trying to print is more than X characters (can't remember what X is). Try just printing a short string (say, 5 characters) and see what happens; then try a long string (say, 100 characters) and see what happens.
