setting button INSENSITIVE

[Gary Scavone <gary ccrma stanford edu>]

I have a button that calls a routine.  If a certain condition exists
in that routine, I want to set the button state to INSENSITIVE.  When
I do this, however, my whole application becomes insensitive ... I
suspect that the button routine is not returning properly after
changing its state.

What would be the proper way to go about this?  Thanks.
