Hi, Recently (maybe after upgrading to IE 10?) the GIB in handviewer does not work for me on this computer. It is available to be "pressed", but does not produce any result. I am using Java 7, update 21. If I turn on debug I see the following error message: Line: 1 Error: Unable to get property '0' of undefined or null reference. If I go further it says: SCRIPT5007: Unable to get property '0' of undefined or null reference handviewer.js, line 1 character 183635. The highlighted section of the script is "{if(deck[suit][c]>=0&&deck[suit][c]!=whosTurn)". Thanks Don
