Screen flickering (40 pages)

Thank you Cabojoe... Often new models have problems that need to be ironed out. But the cracked screen issue seems to be anecdotal so far and may not be widespread. The flickering... that may be more serious and require a software fix.... or it could be a batch of bad parts.

Ouch!
