I have never had this problem on my iPad. Not that that means anything - one anecdote is not data!
So, try the old "kick the iPad in the software" trick to see if you can make it behave better. This means to do either a restart or a reset. Here's how:
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.
Try either (or both!) of those and see if that fixes your problem. Good luck and let us know how you get on.
