I just noticed that my previous response to you wasn't inserted at the 
correct position in the conversation thread. Maybe that is why I haven't had 
a response (hint, hint!). Here it is again:

Your correction (i.e. SaveDefinitions->True) doesn't fully solve the 
problem, because although it ensures that Manipulate is now active, it is 
not as active as I intended it to be.

1. In Mathematica 6 your corrected version shows the behaviour that I 
intended, i.e. a 2D Ising model that continuously updates itself when the 
"update" check box is selected.

2. In Mathematica Player (Windows XP, with no other Wolfram products 
installed) the behaviour is not like this, because the only updating that 
you get is the initial randomisation when you select the "update" check box. 
A little experimentation reveals that if the Player window does NOT have 
focus then the Ising model updates DO occur! Irrespective of the focus of 
the Player window Mathkernel.exe + MathematicaPlayer.exe use almost 100% of 
the CPU time.
