Adobe Illustrator get Not Responding message every time I use Live Paint

Every time I use Live Paint, I get a greyed out screen and Not Responding.  It will clear up after a minute or two, but if I click on something else, even just Edit tab, it does it again.  The live paint tool works, but it slows down my whole computer, even when I try to move on to another part of a design. This happens with every new document.  Any help would be greatly appreciated!  I am still fairly new to Illustrator, so maybe I am doing something wrong.
