Radio button callbacks happening twice and logging

[Jeff Shipman <shippy cs nmt edu>]

Whenever you click a radio button that has not been depressed,
it causes its callback to be executed twice. This can cause
problems with stuff like logging when this callback is called
because I only want things to be logged once rather than
twice. The only thing I've thought of is setting a static
variable and using the value of that to determine whether
to really log or not. This seems rather kludgy to me and
I was wondering if anybody has a better idea?
