Laura an I are travelling accross the Interoceanic road equipped only with our 2 XO-1s loaded with your most excellent os240py image. This bug is most definitively the most annoying and I am so happy you seem to have found a workaround. I´ll probably try to comment out the line in rc.sysinit today and test it.
Thanks for the information! We´ll report as we are preparing "Misky Pachamama" (Sweet Earth) Sugar Camp event in Puno, high in the Andes, in front of the Titicaca Lake. We plan to have a workshop with developers, teachers, and also a translation sprint for Aymara and Quechua languages. Cheers! BTW: Alt-Tab and some other shortcuts, are annoyance nº2 for me. We´ll continue to test and share this image with the community here.
