I have an iPad 2 and no problems. I assume you know the double press the button trick, which brings up all of your open programs, do a long hold on one of them to get to wiggle mode, then start closing them out. I wasn't paying attention and had 20 programs open! Yeah, grandkids. Or power completely off and start over? If you've done that, then that's all I know to do to get the cache cleared out and stuff "cleaned up" a little bit. Good luck!
