This seems to occur frequently. My Zaurus suddenly doesn't register key presses from either the keyboard or the magic buttons (addressbook, calendar, arrows, ok, etc.).
I'm running henteges 3.5.3 on an SL5000d. Every time I suspend, I use the menu (not the keyboard), because of something I read elsewhere.
With this bug I can turn the zaurus on using the cancel key, but I can't successfully do anything keyboard related after that. Ideas?
