Do you have Settings->Display Settings->Fullscreen Mode enabled? I have that enabled, as well as "Hide the Navigation Bar", and if I swipe up to display the taskbar, I can then either swipe up again to hide it, or even just tap in the center of the screen. This is on my BOOX Max Lumi which should, in theory, match your Lumi 2. If you go to your main tablet Settings->Gestures, do you have "Bottom" set to "Navigation Bar"? I can't imagine why we would be seeing such different behavior.

Thanks,
Mike
