[Gambas-user] More null problems

[Stephen Bungay]

   It is the nature of radio buttons to allow only one in a set to be 
toggled on, If you really want to go that route then I would suggest 
that you use checkboxes instead of radio buttons, A better way (IMHO) is 
to place a third button on the form labelled as "Unknown" and set that 
one when the gender is a null.
