If `box' is a ptr-to-widget at this point, then this is good so far...

I suppose this is what you would want `enter_button' to do ?

Is it possible that either 'box' is a wild pointer or that your
compiler is not complaining due to a prior declaration of somthing
like:

static gboolean enter_button = FALSE;


Other than some technical mistake; I dont see anything
fundimentaly wrong with your reasoning.
