Several of the solitaire games have the same bug. When I start a new game, there are times when the Right column of cards does not show up until after I've made a play. This is not ideal since the card in the missing column might be the most advantageous card to play. I have noticed this in both of the Klondike games, the Spider (1Suit) game, Freecell and the Russian Solitaire game.

Also, today, the Russian Solitaire game is not working at all. The fields are all blank.
