Not on my laptop
It works on my 64-bit Windows 7 laptop.
I did have some problems when using it with dual displays - it positioned the window half in one and half in the other, and seemed reluctant to move.

One minor issue:
A couple of times this has happened:
I have played the hand and made the contract. At the end it says I could have made one more trick. Following the annotated play shows it playing exactly the same as me except for a meaningless difference in the precise card played, at which point the defense does not cash all the tricks it can, so it allows an overtrick to be made.
An example is Hand 61 of the NT declarer play group (called "What if East were a good player"). I played the top club on the third club trick to knock out the Ace, the annotated play the low club. In the first case, the defense switches to spades and takes a couple of tricks; in the second it continues Hearts.

When the computer has to play a card, there are two situations:
1.- the script in the annotated play is being followed.
Then the program will select and play the card in the script.
2.- the play did not exactly follow the script.
At that point, the computer's playing engine kicks in and selects the best card it can.
(2) happened when, at trick 5, you played a higher club than the small club in the script.
Then the computer engine stopped following the script and returned a spade (best play).
In the script, East returns a heart, West's suit. This allows declarer to make an extra trick.
I guess I did not fully analyze the deal when I wrote the script. I will correct it in the next
release. Thank you for pointing this out.
The computer playing engine is a DDS (Double Dummy Solver) written by Bo Haglund.
There are several situations where the DDS takes over and makes unexpected or
apparently bad plays, but in fact it will never let you make a trick that you shouldn't.
