I recently bought the Jakks Classic Arcade Pinball plug and play unit. Has anyone else played this thing yet?

It's not the greatest video pinball i've played but it's not bad either. The ball physics are acceptable and the design of the three tables isn't too bad. It's even got multi ball play. That is probably one of the more important things for me when it comes to pinball. Right after ball physics and design.

One problem I noticed with my unit is that the screen will roll every so often during game play. I did not see this happen with the other Jakks units that i've played so I'm wondering if this is a defective unit? I'm curious to find out if others have played this pinball and have had a similar problem?
