O$: click on a Radio Group

[Franco Maregotto]

Hi all
What do you use to prevent the evClick method to be executed when the user
clicks on a RadioGroup over the current value?
I.E.: 3 radio Buttons (say iVarRadioBtn, numeric) currently iVarRadioBtn is
1.
The method should run only if the value becomes 0 or 2.
The only way I found is to monitor this value with another instance
variable. Not very "elegant"

Many TIA for any suggestion
Ciao
