I have no plans on exposing modes for devices that don't have the LEDs to show which mode is selected. The code is still there for you to modify if you want though. Modifying your tablet's definition might be sufficient to achieve that in the future. ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
