My guess is that you're just being a little too "gingerly" with it. That yellow "X" (in a circle, IIRC; but I've not been on my boat for a couple of months now) is the map cursor, and indicates that the plotter thinks you're trying to mark a spot on the chart (such as to enter a waypoint or similar). It comes up when you touch the screen WITHOUT dragging it anywhere. Odds are, you've got a bit of "finger bounce" going on. Just make a point of FIRMLY pressing on the screen then dragging it in whatever direction WITHOUT lifting your finger.
