can't flip deck over again in solitaire

Exactly what it says. I will be in the middle of a game and get to the end of the deck. When I try to flip over the deck to go through it again, it won't let me. This is really frustrating because I want to finish the game. Please fix this, thanks!
Also, I think you should have a hint button that can show you what move(s) are available when you're stuck.
