Casio CZ/ VZ/ FZ - Pro Series

I just got my VZ and well...I'm having too much fun to write a review 
but I will shortly.

My unit does show a problem though with the screen.  Sometimes when I'm 
working in menus the screen get's all out of whack and starts to 
scramble some pixels around and jumble up some of the words.  When I 
refresh the menu it goes away.  

Does anyone else have this problem with their VZ?  Is this a sign for 
bad things to come?

I read an earlier post that spoke about almost the same problem with a 
Hohner series VZ.

Is is a internal problem or just a bug with the system?
