OK, so this is a strange one, albeit not too mission critical.
WHen in Market, I can not see the 'second' preview of any application.
I always can see the first, and if there are more then 2, the 3rd , 4th and so on.
It is really strange.
Steps taken include Stopping processes, clearing cache and data, reboot, power down, freezing market and unfreezing just for giggles.
Its just really strange.
I'd attace a screen shot, but it would just be a black screen.
