Hi, i recently got my iwork 10 with the hipen stylus (which seems to work ok, but does judder around a little so kinda rubbish for handwriting and drawing)
i found that people talked about palm rejection and now having a pen see how necessary it is. The palm rejection is non existent it seems.
So i have looked online and found a workaround that i thought i would share,<b>Tray Touch Toggle</b> on the link below can toggle off the touch screen but keeps the pen active.
