Hi guys: Day two into my new Slate. So far love it. This has happened twice: When docking the slate (screen on). the screen becomes flickering with several lines of color and nothing can be seen on the screen any more. Only a hard boot (recycle with power button hold), got me out of it. Other times, docking with screen on has created no problem. Anyone else have this happen too? Is is software because the dock has an HMDI out? I hope it is not hardware.
