Thanks for the reply. The leader Board is a great idea. My kids love seeing where they are but of course ask questions when they see someone selling average 7000 per fish and we only get 400 - 450 at the very top. I try to teach them not to cheat but here they see it all the time, like I'm sure a lot of other kids do.
I hope you do work the problems out and delete these cheaters. This is a family program for all to enjoy.
Maybe before you release your next version you should do some real testing or give a Beta version to a few to test.
