when I try to open the web or many files I get a box saying "Complete Action Using" and I select one. Then it asks me "Once or Always" I choose Always. Then it says to "Clear default settings by going to Settings> application manager>all I go to settings and that is as far as I get. Where the heck do I find the rest of it? How the heck do I get the tablet to except my choice and not ask me again.
