Default Rainbow lines on screen when dragging

I have a brand new (Christmas gift) Visual Land Prestige 7L
Android Tablet running "Ice Cream Sandwich". It has a 'capacitive screen'.
It was working great until last night (after I read a Nook book with the Nook app). Suddenly there were rainbow colored flashing lights on the screen. I switched back to the home screen - that stopped the flashing lights - but - now whenever I touch the screen there is tiny red dot which develops into a wavy rainbow line when I 'swipe' the screen.

How can I fix this problem? I am a 'newbie' with Tablets - but - I've used desktop computers for years.)
Thanking you in advance for your help.
