Hi the grey box is probably because you have too many Apps running.
It's probably not because of that at all
Double click the Home button, that will show you what apps are open.
It actually doesn't show that at all.
Hold down the individual Apps until you see a minus button on the app and press it. This will not delete your App it will simply close it down and restore capacity in the iPads memory .
Very few of the apps you see there will ever be using any processor time when not open; most of the time, for most people, none of them will be.
Hope this helps
Thanks for trying to help, but it would be better if you did more and better research, and perhaps got a bit more experience with the system, before providing technical answers. The whole topic of multitasking and how it actually works in iOS 4.2.1 has been discussed numerous times in these forums and any number of other venues; my own non-tech explanation is provided as a starting point.
