OLPC of course approves such changes, but the user-interface impact slipped past us at the time. the AVC pads also enable tap-to-click by default, and for uniformity we should have disabled it by default. but it require a different command sequence for disabling, and for various reasons the change didn't happen until today's os7. so the answer to your question is yes, the presence of tap-to-click on your laptops is unintended. it's not out of the question that this could be made user-selectable, but there are no current plans to do so. paul =--------------------- paul fox, pgf(a)laptop.org
