No, not quite

I'm an EPOS Engineer, our computer equipment (Wincor Nixdorf) uses XPe mostly and Linux, but that's for B&Q, when the POS applications run on it, you wouldn't know what operating system was running, because everything's hidden away. No borders, windows, little blue lines at the bottom of the screen or missing graphics.
I can always design my own screen set to cope with any missing graphic strip, or stretch it a bit to fit the full screen, but I can't find a way to hide the operating system and make MACH3 go full screen. I hope someone knows, it's driving me nuts.
