The first thing to try when the iPad acts "hinky" is either a restart or a reboot. To do:
Restart: Hold down the power button until the power off slider appears. Slide it off. When the iPad finishes shutting down, hold down the power button again until the Apple logo appears.
Reset: Hold both the power and home buttons until the screen goes dark and the Apple logo then appears (the slide to unlock screen may or may not appear). Once the logo appears, release the buttons. After a time, your homescreen will appear. Please note that it may take some time for the Apple logo to appear or for your homescreen to appear (or both). This is normal. Eventually, the homescreen will appear.
It's amazing how either of those two things (or both!) help in most cases. However, if it didn't help you, please let us know and we'll try to figure out what's going on. Good luck.
