Hmmm...looks fine here Richard. Try some of my "go to fixes" and see if it doesn't set it right again...
Quit Apps: To quit an app double press the Home button and the Multitasking Tray will appear at the bottom of the screen revealing all of the open apps. Tap and hold any app icon until all of the icons start jiggling. A red circle with a "-" (minus sign) will appear in the upper left-hand corner of each icon. Tap the red circle and the app will close.
Restart the iPad: Press and hold down the Sleep/wake switch on the top edge of the iPad for few seconds until the red slider appears, slide this across to shut the iPad down. Restart the iPad by pressing the Sleep/wake switch until the Apple logo appears.
Reset the iPad: You can do this by pressing the Home button and the Sleep/wake switch on the top the iPad's case and holding them down together for at least 10 seconds, until you see the Apple logo. The iPad should then reset itself. The boot up process takes a few minutes and then the iPad should be responsive again. More here:

Reinstall Apps: While the app is closed press and hold its icon until all of the icons on your screen begin to jiggle. A black circle with an “X” will appear in the upper left-hand corner. Tap on the “X” and confirm that you want to delete the app. Reset the iPad (using the instructions above).
Open the App Store App and tap on "Purchased" in the bottom toolbar. Locate the app you just deleted. Tap on the download button (cloud) and the app will be reinstalled. (Downloading any app already purchased again is free).
Apps that require logins, etc. will need to be set up again. More here:

Hope that helps and let us know how it goes.
