Thanks Stefano, I had understood the operation, I just hadn't realised that I 
wouldn't be allowed to toggle the TRUE button in a pair. By choosing just one 
to set to either TRUE or FALSE, I had expected that the "other" button would 
become the complement of the one I was assigning a value.

My program is switching between mono and stereo for both the input and the 
output. I am storing the required mode in two boolean variables; one for 
input and one for output. I was updating the form controls by writing the 
value of each variable into one of the input and one of the output 
RadioButton controls. This depended on the mono/stereo pairs of RadioButtons 
being updated in a way not supported by Gambas. 

Following your advice I have added two more event handlers (for the "mono" 
buttons) and a few extra lines to figure out which RadioButton must be set to 
TRUE. It is a lot less "elegant" but has the distinct advantage of working 
properly :~)
