Frozen right-side screen when using "mail"

Question

Dear reader
1) A new incoming mail summary appears, as usual, on the left part of your iPad screen;
2) As you finger-activate it, it seems to execute a reading procees, as you would expect;
3) However, the right side of your iPad screen does not show the new message contents;
4) Instead, the right side of your iPad screen remains "frozen", showing photos from an old
    previous message.  The "photos" resist any attempt to move them...
Thank you,
Thierry

Try quitting the app and the restart the iPad.
Go to the home screen first by tapping the home button. Quit mail by double tapping the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on the mail icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
If that doesn't work, rest the iPad.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
